Like Surfaces
What is a good project that relates to water?
Need to perform a ten minute powerpoint presentation that somehow relates to water. Like surface tension, things like that. Any idea?
well there is always floating a steel paperclip on water, which should sink because its denser than water but surface tension keeps it afloat
if that doesn’t work you could use water to crush a soda can with atmospheric pressure, put a bit of water in the can, boil the water out but not completely, then (with tongs) flip it over into a pie plate of water, top first, it will crush instantly because the gas gets cooled into a liquid and more or less makes a vacuum and the atmosphere crushes the can
then if you have a pool you can fill a balloon and pull it underwater to shrink it
