Gender Reveal Smoke Bombs: The Complete Planning Guide
Published Last updated
Last updated
Gender reveal smoke bombs are the most popular way to announce a baby's gender, and for good reason: a dramatic burst of pink or blue smoke makes an unforgettable moment and the kind of photos people actually frame. Every Shutter Bombs grenade is an Enola Gaye unit with a non-toxic, cool-burning formula (smoke, no open flame). This guide walks you through choosing the right grenade, planning the shot, buying the right quantity, and keeping the color a complete secret until the wire is pulled.
Best Smoke Grenades for Gender Reveals
All four of these are wire-pull or top-pull Enola Gaye grenades available in both pink and blue. Pick based on how big the moment is and how long you need the smoke to last.
The Headline Pick: Gender Reveal WP40 (Discreet Labels)
The Gender Reveal WP40 is the product built specifically for this article's whole purpose: keeping the color secret. It is the 90-second WP40 platform - the longest burn in the 40mm family - but shipped in plain, discreet packaging so neither parent can spot the color before the pull. One WP40 is enough for the reveal itself, but most couples keep 2-3 on hand for multiple angles.
For Small, Intimate or Multi-Person Reveals
The EG25 Micro Gender Reveal 3-pack is the budget-friendly, discreetly labeled option. Each EG25 micro can burns for about 25 seconds - perfect for a quick, punchy reveal. Hand one to each parent (or each grandparent) and have everyone pull at the same time for a synchronized group burst.
For Dramatic Photo and Video Reveals
The standard WP40 Wire Pull Smoke Grenade delivers 90 seconds of dense colored smoke - the most forgiving option for a photographer who needs time to work the angles. If you are choosing colors yourselves rather than keeping them secret, this is the workhorse for sustained, frame-filling clouds.
For Maximum Instant Impact
The Twin Vent II vents from both ends at once, dumping its entire charge in about 25 seconds for the densest, widest instant cloud we make. This is the "hero shot" can - perfect for the actual reveal frame when you want maximum visual punch in the first few seconds.

How to Plan Your Gender Reveal
A great reveal is mostly logistics. Run through these five steps and the moment itself takes care of itself.
-
01Keep the Gender a Secret
Have your doctor write the baby's sex on a slip and seal it in an envelope. Hand that envelope to one trusted friend, family member, or your photographer - and stay out of the loop. They order the matching discreet-label grenade so both parents are genuinely surprised.
-
02Choose Your Grenade and Color
Pink for a girl, blue for a boy. The 90-second Gender Reveal WP40 is ideal for photos; the EG25 Micro 3-pack suits quick or multi-person reveals; the Twin Vent II dumps a huge cloud instantly.
-
03Pick Your Location and Time
Outdoors with a light breeze is ideal - the wind carries smoke for dramatic trails. Open fields, beaches, parks, and backyards all work. Avoid enclosed spaces and clear the area of dry brush and flammable surfaces. Golden hour (about an hour before sunset) gives the best light.
-
04Set Up the Shot
Brief your photographer beforehand and get them in position first. Frame so the smoke drifts into the shot, and have the couple face each other or the smoke (not the lens) for natural reactions. Have someone hold the grenade at arm's length, facing downwind.
Safety NoteNever point the grenade toward your face or body. Smoke exits at force and can stain. Point it downward or away at arm's length, well clear of guests and clothing.
-
05Pull the Wire and Capture the Moment
Hold the body and pull the ring firmly to the side - never straight up. Smoke begins immediately, with no delay and no sparks. Let it build for 2-3 seconds before reacting, then shoot in burst mode. The first 10-15 seconds produce the densest smoke; move around for different angles as the cloud grows.
How Many Smoke Grenades Do You Need?
Always buy a couple of extras. A spare grenade is cheap insurance against a misfire, a gust that thins the cloud, or wanting one more take. Here is a rough planning guide by reveal type.
| Reveal Type | Recommended | Why |
|---|---|---|
| Simple couple reveal | 2-3 WP40s | 90s burn gives the photographer room to work multiple angles |
| Family reveal (everyone participates) | 1 EG25 Micro 3-pack | Three discreet-label micro cans, one per person, pulled together |
| Dramatic photo/video session | 1 Twin Vent II + 2-3 WP40s | Twin Vent for the instant hero cloud, WP40s for sustained portraits |
| Big party reveal | 2 EG25 Micro 3-packs (pink + blue) | Stage a decoy color, then drop the real one for a double beat |
Pro insight
For a full photo session - reveal moment plus walking shots, portraits, and editorial close-ups - plan on 6-8 units. The reveal itself is best with 2-3 grenades fired at once. For an exact count by use case, see how many smoke bombs you need.
Smoke Bomb Colors for Gender Reveals
Pink and blue are the definitive reveal colors, and both are stocked across every Shutter Bombs format. But you are not limited to two cans:
- Girl: Pink smoke - the classic, and it photographs beautifully against green, sky, or neutral backdrops.
- Boy: Blue smoke - bold and high-contrast, especially against lighter scenery.
- Decoy/pre-reveal: Fire a neutral white or purple grenade first to build anticipation, then drop the real color. White gives a clean dramatic cloud; purple adds bold contrast.
Shutter Bombs carries all 9 Enola Gaye colors - black, blue, green, orange, pink, purple, red, white, and yellow - so coordinating a full sequence is easy. For deeper picks, see the smoke bomb color guide and the dedicated pink smoke gender reveal walkthrough.
Safety Tips for Gender Reveals
- Outdoors only. Never use a smoke grenade inside a home, barn, tent, or covered venue.
- Keep away from dry vegetation. Especially in summer. The can gets hot during and after the burn.
- Hold by the base. The formula is cool-burning with no open flame, but the can itself heats up - hold it at the base, ideally with gloves, and don't hold it for the full burn.
- Mind your clothing. Colored smoke can stain white and light fabrics. Wear dark colors near the vent. (More on this in do smoke bombs stain clothes.)
- Adults only. Only adults should handle and activate grenades; keep children well back and upwind. You must be 18+ to buy.
- Have water on hand. Submerge a spent or misfired unit in water before disposal.
- Check the wind. Stand upwind so smoke blows behind the group, not into faces.

Frequently Asked Questions
Are gender reveal smoke bombs safe for pregnant women?
Enola Gaye smoke grenades produce colored, non-toxic smoke, but sensible precautions still apply, especially for pregnant women. The safest approach is to have someone else activate the grenade entirely - the person igniting should wear gloves, and activation produces colored smoke immediately with no sparks. Pregnant women, children, and anyone not involved should stand well back and position themselves upwind so smoke blows away from the group. The 90-second Gender Reveal WP40 gives the expecting parents plenty of time to enjoy the moment from a comfortable distance. Never stand directly at the smoke vents during the burn.
Can I do a smoke bomb gender reveal indoors?
No - smoke grenades must be used outdoors only, no exceptions. Even a single can produces an overwhelming volume of dense smoke in an interior, and the can generates heat at the vents during the burn. Covered patios, barns, and tents are also unsuitable. For the reveal, find an open outdoor spot away from dry grass, wooden decks, or any flammable surface. With a proper outdoor setup, smoke reveals are stunning on camera and safe for guests keeping a sensible bystander distance. If you need an indoor option, see can you use smoke bombs indoors for alternatives.
How do I keep the gender a surprise?
The most reliable method starts at the doctor's office: ask your provider to write the baby's sex on a slip and seal it in an envelope. Hand that envelope to one trusted friend, family member, or your photographer, and stay out of the loop. That person orders the correct color - pink for a girl, blue for a boy - in the discreetly labeled Gender Reveal WP40 or EG25 Micro 3-pack, both of which ship in plain packaging so the color never gives itself away. Your helper receives the package and brings the grenade to the reveal, handing it over - or activating it on cue - without anyone spotting the color first.
What if it is windy on reveal day?
A light breeze is ideal for gender reveal photography - it creates flowing smoke trails and keeps the cloud from sitting flat on the ground. Work with the wind: position the group so the wind is at their backs, directing smoke away from faces and into the frame behind them. For stronger wind, the Twin Vent II is worth considering - its dual-vent design releases a wider, denser cloud immediately at activation (about a 25-second burn), so you still get an impactful visual even when dispersion is faster than usual. Always bring backup units, keep bystanders at a safe distance, and never put guests directly downwind of the activation point.
How far in advance should I order smoke bombs for a gender reveal?
Order at least 10 to 14 days before your event. Shutter Bombs ships all smoke grenades via certified hazmat ground (FedEx/UPS) from a Nevada warehouse to the contiguous US except Massachusetts, typically arriving in a few business days depending on location - there is no express, overnight, or air option. A few extra days of cushion protects you from carrier delays. Ordering more is also smart financially: hazmat ground fees step down as your order grows ($40 under $125, $30 from $125, $15 from $175), and shipping is FREE on orders of $225 or more. Note that we do not ship to Alaska, Hawaii, Puerto Rico, Canada, international addresses, or PO boxes, so plan accordingly near holidays or weekends. See hazmat shipping and state legality for the full policy.
Can my photographer safely hold a smoke grenade during the reveal?
Yes, with care. The formula is cool-burning with no open flame, but the can itself gets hot during and after the burn - hold it by the base, wear gloves, and don't hold the device for its full burn duration. Pull the wire ring firmly to the side in one smooth motion, never straight up. Staining risk exists near the vent, so the holder should keep the vent pointed away from their body and clothing at all times. The 90-second WP40 single-vent is the standard choice for photographer-held shots; for a wider instant cloud without aiming a vent, the Twin Vent II is a strong alternative.
Will the smoke stain my clothes?
Colored smoke can leave temporary residue on white or light-colored fabrics if you stand close to the vent. The fix is simple: wear dark clothing for the reveal, designate someone else to hold the grenade, and keep the vent pointed away from everyone. Most residue rinses out of fabric and off skin with soap and water. For a deeper look, read do smoke bombs stain clothes.
What if I live in a state that restricts smoke bombs?
Shutter Bombs products are CE Approved and ATF Compliant, and no license is needed to buy or use them in most states. We ship to the entire contiguous US except Massachusetts, and we do not ship to Alaska, Hawaii, or Puerto Rico. Always check your local and state rules before use - and note that national parks generally prohibit smoke devices. Our state legality guide has the details.
