You need a film capsule old school- basically a small little cylindrical vehicle of destruction. remove the cap, and place a rubber stopper betwixt the opening,

for now just set it aside- Do not start the experiment with the rubber cork on- REMOVE IT!

INSTRUCTIONS: THE EXPERIMENT

You take the film canister and fill it half way with 21 degree celcius water, this is very important!

Rember the rubber stopper that we asked you to put aside, Here's where it comes it!!!!

Now! Take your water filled film capsule, and place one single alka-seltzer tablet down the opening- quickly close the lid;


Quickly put the film capsule lid-side down on a flat surface, and behold the increadible might of Alka-Seltzer rocket feul with god's devine H20.
