One of the most famous products for science classes is the Geyser Tube™. If you have tried to drop a Mentos candy into a bottle of soda without it, you probably got soaked, and maybe even missed the entire geyser. With this gadget, you will be sure to get the perfect launch while staying clean and dryA "and see the Mentos and soda reaction for yourself every time.The Geyser Tube™ attaches to any plastic two-liter soda bottle. (Diet soda works best because it does not leave the sugary, sticky mess behind). Secure the trigger pin, then load the Mentos into the tube. Once you have locked the pressurizing nozzle in place, pull the pin and clear the area! When the Mentos drops, the soda geyser will shoot as high as 30 feet.Two things make this Geyser Tube™ better than all the rest. First is the trigger mechanism. The double-pull pin action gives you time to move out of the way and ensures a tight seal for the best buildup of pressure. Second is the three caps that create different geyser shapes. Have your students compare and contrast the Fountain, the Fan, and the A Runaway." Your Geyser Tube™ comes with a roll of Mentos. All you need is a plastic bottle of soda.

Welcome to an awesome Science-At-Home activity where you’ll have fun exploring some of the scientific properties of air and water as you create a tornado in a bottle. An exciting experiment featuring a close-up look at a tornado vortex.

Welcome to an awesome Science-At-Home fun activity where you’ll have some fun making spooky sounds and learning about the “science of sound.” It’s all about inertia, sound and vibration in this cool kit.

• How It Works: Thanks to the laws of inertia and some centripetal motion, the penny flips up on its edge and spins around the inside of the balloon. However, try substituting one of our hex nuts for the penny and you get a screaming balloon! The unique shape of the hex nut vibrates the walls of the balloon to produce a wonderfully annoying sound.
  
• Get hands-on with science at home
  
• Learn about centripetal force and the science of sound
  
• A memorable & attention grabbing lab, both visually and audibly
  
• A fun science activity to stay engaged with learning at home
  
• What’s Included:
  
• 12 clear, latex balloons
  
• 8 zinc hex nuts
  
• Step-by-step activity guide

Last time we checked, rocket fuel is still a no-go in the classroom, and that’s why Flying Film Canisters are so cool! A simple mixture of the Flat Fizzers and water results in an explosive, rocketing film canister that would make NASA jealous. These plastic, super-sturdy canisters are the best we’ve ever seen, specially made to ensure the biggest, best pop every time.How much water does it take to create the biggest launch? How much of a Flat Fizzer do you need? You’ll have to test mixtures to be sure! Don’t settle for regular film canisters that don’t give you the pop you need. Get your hands on the Flying Film Canisters and blast off!What Does It Teach?When you have gas building-up in an enclosed space, what happens? Wait… don’t answer that. More specifically, what happens when CO2 builds up in a closed film canister? Simple – an explosion so fun you won’t want the popping to stop. The key to the fun is the Flat Fizzers. These tablets are made of sodium bicarbonate (baking soda) and citric acid. These non-toxic components dissolve and mix in water, creating carbon dioxide. The gas is too much to contain in the closed canister and it builds until:3… 2… 1… You know the rest.

• Film canisters for all your experiments!
  
• Use with our Flat Fizzers and water to make a rocketing film canister
  
• An explosive lesson in air pressure and motionWhat’s Included?
