5.18.17// Some notes on polymers!
[3/11/17-4/14/17] ↳ Science 8 notes! This was from our unit on carbon.
Cartesian Diver (Dec. 8, 2011)
Cartesian Diver (Dec. 8, 2011)
Materials:
Soda bottle (empty)
Bendy straw
Rubber band 5 paper clips
Soda bottle:
Diameter=17
Radius=8.5
How to make:
Bend the straw on the top where the openings are even
Tie sides together with the rubber band, but make the holes have air
Attach the 5 paper clips to the rubber band
Test the diver in a little bit of water, and make sure it stands
If that works, full up the soda bottle full, drop the diver in, and close it shut
Shake the bottle to add pressure
If you have successfully completed the experiment, when you push on the sides of the bottle, the diver should go down, and when it's left alone it will float back up
Results:
If all goes well, squeezing the bottle will force the diver to dive, and no pressure will make the diver shoot up
