Hands-On Science

Rocket Science: Rocket Poppers

Rocket poppers are easy to make and a lot of fun. Even grownups like to play with them. They can be used indoors if you have a room with a high ceiling and you don't mind a messy floor, but outdoors is the preferred environment.



Once you demonstrate how it works, everyone will one to try it for themselves.

Begin by opening up a seltzer packet so that the tablet is at hand. Next, open the film cannister, and pour a small amount of water into the cannister. Drop the seltzer tablet into the cannister, snap the lid in place, and put the cannister lid down on the ground. Step back. After a few seconds, the cannister will leap into the air with a pop!
