Step by Step Instructions for an Amazing Gender Reveal
Published Last updated
Last updated
Smoke bombs have become one of the most popular ways to announce a baby's gender. The concept is simple: when the grenade is activated, it emits a steady cloud of colored smoke — pink for a girl, blue for a boy — that fills the frame for a dramatic, photo-ready reveal. They work beautifully on their own or alongside balloons, confetti, or a sealed announcement box.
The smoke grenades sold by Shutter Bombs are manufactured by Enola Gaye — non-toxic, cool-burning, and rated for 10+ years of shelf life when stored cool and dry. You don't need any special equipment or training to pull off a great reveal. With a little planning and careful handling, even a first-timer can create a stunning display. This guide walks you through it step by step.

Gather Your Supplies
The first step is gathering everything you'll need. Smoke bombs are the centerpiece, but a few extra items make the moment land harder. Props like large balloons filled with pink or blue confetti add a second beat of excitement when they pop. Banners or signs reading "It's a Boy" or "It's a Girl" double as decor before the reveal and as keepsakes afterward.
If family lives far away, set up a video call ahead of time so they can watch live. FaceTime, Zoom, or any group video platform works — just have one person hold a phone steady and frame the wide shot so remote guests see the cloud the moment it goes up.
For the most dramatic photos, choose the Gender Reveal WP40 — it delivers a full 90 seconds of dense pink or blue smoke, giving your photographer time for multiple angles and poses. Both come with discreet labels so whoever sets it up never sees the color. For group reveals, the Gender Reveal EG25 3-Pack puts a grenade in three hands at once for a wall of color.
Create a Colorful Palette
One of the more important decisions is your color palette. Pink and blue are the classics, and for good reason — they read instantly and photograph cleanly against most outdoor backgrounds. The pink WP40 in particular produces a saturated, camera-friendly cloud that holds its color well in daylight.
If you want to layer in your party's look, coordinate the surrounding decor — neutral whites, soft greens, or metallic gold centerpieces all let the pink or blue smoke stay the star without competing for attention. Keep the reveal smoke itself to a single secret color, though: the whole point is the surprise, so save mixed or contrasting colors for celebration props rather than the grenade.
Set Up the Scene
Setting the scene is often the difference between a forgettable reveal and one people talk about for years. Start with location. You want an open outdoor space with room for the smoke to spread and a clean backdrop for photos — a backyard, an open meadow, or a quiet shoreline all work well.
Before you commit to a public spot, check the rules. Many city parks and beaches prohibit pyrotechnics, and national parks generally ban smoke devices altogether. A private backyard or a venue that has given you written permission is the safest bet. Our state legality guide and legality overview walk through what to confirm before you light anything.
Once the location is locked, add personal touches — themed decorations, props, and a clear staging spot for the person activating the grenade. Thoughtful framing here pays off the second the smoke goes up.
Position your subjects with the sun behind the photographer so light hits the smoke cloud from the front. Backlit smoke looks washed out. Check wind direction beforehand — you want smoke drifting across the frame, not toward the camera or away from it.
Prepare to Use Your Smoke Bombs
Preparing properly is what keeps the reveal smooth and safe. Before activation, take a few precautions so nothing catches you off guard.
First, always check local laws on smoke device use before any display. Be aware of your surroundings and the wind direction when choosing where to stand. Only adults should handle these devices — the Gender Reveal WP40 uses a wire-pull ignition, so pull the ring firmly to the side, never straight up, with about 5 to 8 pounds of force. Have a plan for disposing of the spent unit afterward, and keep a bucket of water nearby in case a grenade misfires. For the full procedure, see our ATF compliance and ignition guide.
Always wear gloves and eye protection during activation — sparks appear for 1–2 seconds at the moment of the wire pull. Keep the vent pointed away from your body, keep bystanders back, and never hold the grenade for its full burn. The can gets hot, so hold it by the base or place it on non-flammable ground. Avoid use near dry grass or wooden decks, and have a non-pregnant family member handle activation.
Capture the Moment with Photos and Videos
The best way to relive a gender reveal is through photos and video. From the rush of color in the air to the reactions around it, this is a moment you'll want frozen perfectly. Enlist a friend or family member with a camera or phone who can shoot from a clean angle, and make sure they know which color to expect so they can dial in exposure for vivid pink or blue.
For video, mix close-up and wide shots so you have variety when you cut footage together later. Have someone capture sound too — the cheers and reactions are half the magic. If you can spare two people, one shooting stills and one on video gives you the most usable content, and the WP40's 90-second burn leaves plenty of runway for both.
Make sure whoever is filming has free storage and a charged battery. With a little practice beforehand, you'll capture the reveal cleanly the first time. Our complete photography guide and the camera settings guide go deeper on dialing in the shot.
Set burst mode with a shutter speed of at least 1/500s to freeze the initial color burst. Shoot in RAW for richer pink and blue tones in post. For video, use 60fps or higher so you can slow down that first dramatic plume in playback.
Share the Joy
The whole point of a smoke bomb gender reveal is sharing the moment with the people who matter. A great way to amplify it is to gather everyone for a small celebration — a backyard get-together, a park picnic where smoke devices are permitted, or a private venue.
For something extra special, build creative decor around the announcement. Pink or blue balloons and a celebratory banner are easy wins. If you want to go further, set up a small photo station with fun props so guests leave with keepsakes of the day. However you celebrate, the smoke reveal gives you the centerpiece shot everyone will remember.

Frequently Asked Questions
Which smoke bomb is best for gender reveals?
The Gender Reveal WP40 is the top choice for gender reveal photography. It delivers a full 90 seconds of dense, vivid pink or blue smoke and ships with discreet labels so whoever sets it up never sees the color. For reveals where the whole group participates, the Gender Reveal EG25 3-Pack puts a grenade in three hands at once for a wall of color. Each EG25 burns for about 25 seconds — plenty for a coordinated group moment. For maximum impact, pair a WP40 with a Twin Vent II, which vents from both ends for an immediate wide cloud while the WP40s sustain color around it. All of these are available in pink and blue.
Are gender reveal smoke bombs safe?
Enola Gaye smoke grenades, sold by Shutter Bombs, are non-toxic, cool-burning, CE Approved, and ATF Compliant, making them legal for adults 18 and older across the contiguous US except Massachusetts. Proper safety protocol is still non-negotiable. The person activating must wear gloves and eye protection, since sparks appear for 1 to 2 seconds at the moment of the wire pull. Keep the vent pointed away from your body, never place any body part near the smoke outlet, keep bystanders back, and never hold the grenade for its full burn. The can gets hot, so hold it by the base. Avoid use near dry grass or wooden decks, use outdoors only, and have a non-pregnant family member or friend handle activation.
How many smoke bombs do I need for a gender reveal?
It depends on the style of reveal. For an intimate couple reveal focused on photography, two to three Gender Reveal WP40 units give you 90 seconds of dense smoke each, leaving ample time to work through multiple poses. For a larger group reveal where everyone participates at once, one Gender Reveal EG25 3-Pack puts a grenade in three guests' hands for a synchronized wall of pink or blue. For extra drama, add a Twin Vent II — its dual-vent design releases a wider cloud instantly as the opening anchor while supporting units fill the surrounding space. Always keep at least one backup unit on hand in case of a misfire. Our how-many-do-I-need guide breaks this down further.
What is the safest way to activate a smoke bomb for a gender reveal?
Put on gloves and eye protection first. Hold the grenade firmly in your dominant hand with the smoke vent pointed away from your body and toward open ground, never toward guests or the photographer. For the Gender Reveal WP40, grip the wire and pull it firmly to the side — at roughly 90 degrees away from the device body — in one smooth, decisive motion with about 5 to 8 pounds of force. Do not pull straight up. Sparks appear for 1 to 2 seconds immediately after activation, so keep your face and free hand clear. Once smoke begins flowing, hold the unit low at arm's length by its base or set it on non-flammable ground. Never bring the vent near your body or face, never hold the unit for the full burn, and keep all bystanders back.
Should I practice activating a smoke bomb before the gender reveal?
Yes — a test pull before the event is a genuinely good idea, and Shutter Bombs' 100% Product Guarantee makes it easy to justify buying one extra unit for exactly this purpose. Activating a smoke grenade for the first time in front of a crowd introduces unnecessary hesitation. A practice run builds muscle memory for the correct firm side-pull, confirms your gloves and eye protection are in place, and shows you how quickly the sparks appear and smoke begins flowing so you aren't startled in the moment. Test in the same type of outdoor environment you plan to use, ideally at the same time of day, so you can also see how wind affects the smoke drift. If your test unit misfires, contact Shutter Bombs and we'll make it right.
What camera settings capture the gender reveal smoke moment best?
Set your camera to burst mode with a shutter speed of at least 1/500s to freeze the initial burst of color without motion blur. The first 5 to 10 seconds of a WP40 activation produce the most saturated smoke, so your camera must be framed, focused, and actively shooting before the ring is pulled. Pre-focus on the spot where your subject will stand and lock exposure in advance so the camera isn't hunting mid-reveal. Shoot in RAW if you can — the vibrant pink or blue tones respond well to subtle post-processing. For video, 60fps or higher allows smooth slow-motion playback of that first plume. Because the WP40 burns for a full 90 seconds, even if you miss the opening seconds there is plenty of time left to capture great frames.
How do I make sure the gender reveal photos look great?
Lighting and positioning make the difference between a good reveal photo and an exceptional one. Position the photographer so the sun is behind them, illuminating the smoke cloud from the front — backlit smoke looks gray and washed out rather than the vivid pink or blue the WP40 or Twin Vent II produces. Keep guests on the sides of the frame rather than between the camera and the subject so the cloud stays the dominant element. Shoot in an open outdoor space with clearance for the smoke to expand. Wind direction matters: position subjects so wind carries the smoke across the frame rather than directly at or away from the camera. Staining risk is minimal at a sensible distance from the vent, so guests can stand comfortably — and the smoke rinses out of most fabrics with soap and water.
