Pictures of the boys doing Alka Seltzer Rockets or Film Cannister Rockets

 My Webelos Cub Scout Den LOVED doing Alka Seltzer Rockets.  They ended up doing it the whole hour of Cub Scouts.  That was not the plan, but they were having too much fun experimenting with different amounts of water and Alka Seltzer tablets.  It is amazing how high these little things go up in the air.


Use the clear film cannister containers, and break the alka seltzer tablets into 4 pieces.  They need to put about 3/4 inch water in, 1/4 tablet, seal quickly, and put on the ground upside down.  For complete instructions, see my other How to article on this blog.
