Fab STEM Activity

Watery paint, plastic film canister containers with push down lids and Alka Seltzer tablets!

You will need to be outside with these! Place half a tab in a container and fill 1/3 with watery paint. Pop on the lid quickly and place lid down on paper. Quickly stand back and see your rocket launch! Then see your the explosion in paint!

Lots of tinkering can be done here and experimenting. Changing the amount of water/paint and tablet for example will all affect how high the rocket goes. And there is plenty to discuss, chemical reactions, gases, pressure, force, gravity and so on. For the very young it’s just fascinating to watch!
