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.

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 party 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!

Turn our famous gooey slime and vampire veins from an eerie green to blood red as you reveal a vampire’s favorite snack. The secret? It’s a special dye that looks green under normal light and glows an eerie color under black light. It then turns blood red when you hold it up to ordinary white light. Wow!

You’ll receive all the supplies needed to make 24 shaker cups filled with Vampire Slime. It’s the most original take-home party favor you’ve ever seen. You’ll also learn how to make color-changing vampire veins that are guaranteed to make your guests scream with delight. Finally, you’ll learn how to capture a spooky, glowing image on a piece of phosphorescent paper using a battery-powered black light wand.

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.
