Canister Experiment.

Canister Experiment

You will need (Materials) 

• One empty 35mm plastic canister and lid. 
• One fizzing aspirin tablet
• Water

What to do (Method)

1. Head outside.
2. Break the aspirin tablet in half.

   Do the next 2 steps quickly
4. Drop the tablet half into the canister and snap the cap onto the canister (make sure that it snaps on tightly.)
5. Quickly put the canister on the ground CAP SIDE DOWN and STEP BACK at least 2 metres.
6. Stand back and watch!

Variables

We were going to investigate to see if the amount of the tablet will cause the canister to go higher.

What do I think will happen? (Hypothesis) 

I think that when we put in one tablet the canister will not go that high but will still go high.

I think that when we put in 1 ½ tablets the canister will go higher than one whole tablet.

What happens (Results)

Variable	What can you see? Hear? Smell?
1 Tablet.	I heard the canister pop, and saw the canister go flying off of the lid.
1 ½ Tablets.	I did not hear the canister pop this time but I saw the canister go flying off of the lid higher than the one tablet, the canister lid was very sticky.

Conclusion

I noticed that using 1 ½ tablets was better than using 1 tablet.
The 1 tablet did not go as high as I thought.
