The Water Bottle Grenade PSI Experiment

This Instructable is for my Science Fair Project. I'm testing how much Baking Soda and Vinegar I need to get the best PSI, subsequently making the best explosion. Unfortunately, for this experiment, I won't be exploding any bottles. If you do want to see exploding bottles, go somewhere else. Now, to the science.

Water Bottle (The Anorexic Kind) - You can get these from your friends. (Or, if you don't have any, find a recycling program)

Baking Soda - I'm hoping to get it from my FACS teacher, but obviously you can get it at any supermarket for cheapie cheapie.

Vinegar - I'm also getting this from my FACS teacher, but you can get it at any supermarket.

Kleenex - You know what I'm talking about

Gas Pressure Sensor - I'm getting this from my science teacher. You're on your own.

To get the baking soda in the bottle all at the same time, we have to roll it up in Kleenex. Put 6 Kleenexes out on the table and pour these amounts of baking soda on the the Kleenexes. Roll them up like in the pictures.

10g of baking soda

20g of baking soda

30g of baking soda

35g of baking soda

40g of baking soda

45g of baking soda

To test the PSI, we need to use a Gas Pressure Sensor. I'll call it a GPS from here on out. We're going to take a rubber stopper that fits in the water bottle hole and attach your GPS nozzle thing to it.

Measure out your vinegar and pour it into the bottle. Get your first Kleenex ready. Get your data collector ready. Plug everything in and make sure everything works.

Drop your Kleenex in and quickly place the rubber stopper on. The pressure will get really high, sohold it really tightly. Do all six, and you're done!
