How to Make Boo Bubbles – Fog Bursting Bubbles
Bubbles are cool, but bubbles filled with smoke are even cooler! Just imagine the skyrocketing cool factor when you can bounce and play with these bubbles, too. Steve Spangler Science’s famous Boo Bubbles are what you get when you fill a bubble with a carbon dioxide cloud using a cloud bubble generator (that we’ll show you how to make). We saved the best for last: you’ll also learn how to roll and bounce the bubbles in your hands. Whoa! It’s the combination of science AND performance art.
With this Halloween experiment, you’ll be able to test your skills and show off your moves. It’s a great Halloween activity for kids who love to dance, play, juggle, or get their energy out with bubbles that bounce!

The Famous Exploding Pumpkin Science Experiment and Instructions
Just consider it a new way to carve a pumpkin at Halloween. In this Halloween science activity, your pumpkin is carved in the traditional way. However, this pumpkin science experiment has a twist: a chemical reaction is triggered inside the pumpkin, and those previously carved pieces are literally blown out of the pumpkin. Boo-yah!
For this pumpkin science experiment, it’s best to have a trained professional set up and run this lab. Even with a professional, it’s also advisable to have safety personnel available for the duration of the pumpkin experiment. We want to make sure everyone has a safe and fun Halloween party.

Oozing Pumpkin Science Experiment
Have a “gourd” time on Halloween with our Oozing Pumpkin Halloween science activity that is guaranteed to get them talking. This is an awesome new Halloween twist on our kid-friendly Elephant’s Toothpaste experiment. In this Halloween-themed application, you’ll have some awesome foaming ooze seeping from the face of your jack-o’-lantern — as well as squeals of excitement coming from the faces of your audience.
This Halloween activity for kids can create a mess, so take precaution beforehand in dressing up your classroom or other space with something to catch the ooze. Consider adding some food coloring to this pumpkin experiment to give your “ooze” a glow, or make this in a jar for a bubbling wizard’s brew!

Science Halloween experiments and parties just wouldn’t be the same without a few gallons of fake blood. There are tons of fake blood recipes floating around, but the biggest complaint is that the fake blood looks nothing like real blood. Here is a Halloween science activity that is guaranteed to make realistic-looking fake blood. However, any good scientist knows that it takes a bit of experimentation to create something that’s just your (blood) type!
With our fake blood Halloween science activity, we break down the different ways that you can concoct your own. Some of our fake blood recipes are made with edible products, which makes them safe to drip from mouths. Included in our fake blood Halloween experiment is also a recipe that involves chocolate syrup — just like in old-fashioned monster movies!

DRY ICE INFO
Remember these safety rules when using dry ice:
- Dry ice is not a toy. It is for demonstration purposes only
- Only use dry ice with adult supervision
- Always wear safety glasses when handling dry ice. The debris is extremely dangerous to your eyes
- Dry ice must be handled using gloves or tongs because it will cause severe burns if it comes in contact with your skin
- Never put dry ice in your mouth
- Never store dry ice in an airtight container. As the dry ice turns from a solid directly into a gas, the gas will build up and the container will explode. Make sure your container (a Styrofoam chest works well) is ventilated or has a loose-fitting lid
- Do not store dry ice in a freezer. It will cause your freezer to become too cold and your freezer may shut off. On the other hand, if you lose power for an extended period of time, dry ice is the best way to keep things cold
- In the unlikely event of a dry ice burn, treat it the same as you would a heat burn. See the doctor if the skin blisters or comes off. Apply antibiotic ointment to prevent infection and bandage mild burns
Where to Purchase Dry Ice
Some grocery stores will sell dry ice to the public (especially around Halloween) for approximately $1.50 per pound. Dry ice is typically sold as flat, square slabs a few inches thick, or as cylinders that are about three inches long and about a half an inch thick. Either size will work fine for your dry ice experiments.
Remember the science when purchasing dry ice: dry ice turns from a solid into a gas in a process called sublimation. In other words, the dry ice in a grocery bag will literally vanish in about a day. The experts tell us that dry ice will sublimate at a rate of five to 10 pounds every 24 hours in a typical Styrofoam chest. Again, it’s best to purchase the dry ice as close to the time you need it as possible. This is the one time when last minute shopping is necessary. If you are planning to perform several dry ice demonstrations, purchase five to 10 pounds.
