Pop Top Rockets
Just add water, snap the lid shut and stand back! The bubbling action of the chemical reaction builds up pressure inside the can until the top POPS and flied through the air.
Mix up your own top-popping fuel mixture and put the Snap Cans to the distance test. Attach the foam rocket to the Snap Can and shoot the rocket high into the air.
Don't let all of this high-flying fun fool you -- it's a lesson in chemical reaction that will have the young scientist screaming "Lets do it again!"
