Science Experiments & Activities

Red, White, and Blue Soda Geysers
Keep the summer doldrums away by shooting Red, White and Blue Soda Geysers using a Geyser Tube, Mentos, 3 bottles of Diet Sprite or another clear soda. Color two of the sodas using red and blue food coloring. Strawberry soda and blue Mountain Dew Voltage also work. Drop the Mentos in for your own daytime fireworks show.

Mentos Super Soda Dispenser 3000
Use the power of Mentos and Diet Coke to fill 6 glasses at once. It's a fun, creative, hands-on way to utilize the epic Mentos Geyser in a way that harnesses it for your drinking pleasure. 

Smoke Bomb Smoke Rings
The trash can smoke ring generator is a signature finale in Steve Spangler's stage show and was recently featured on the Ellen DeGeneres Show. Everyone always wants to know how to make Steve's classic giant smoke rings… now you can make them at home with a special 4th of July twist!

Dry Ice Smoke Rings 
These cool Mini Smoke Ring Launchers use items you will find in your kitchen and local grocers (dry ice). You'll be launching rings like a pro in no time.

Color Changing UV Beads
Test the power of your sunscreen or just monitor the intensity of the sun with a red, white, and blue UV Bead bracelet. Purchase a packet of red UV beads and string them on blue cord. The sun sensitive beads start out white inside the house, then turn red in the sunlight. Get it? Red, white and blue for the Fourth.

Defraction Grading with Fireworks Rainbow Glasses
When the fireworks start, pull out your Fireworks Rainbow Glasses to see the display in a whole new light. You’ll never want to watch another fireworks display with your naked eye again.

White Lightning Stick
