Just how strong is ice?? Let's find out! To do this experiment, you'll need a can of soup and a can-opener, a bottle top, several pencils, and lots of clear or black electrical tape.
The first
step is to open the can of soup almost all the way. Leave just enough so the top stays attached ... maybe about one centimetre. Then dump out all the soup and fill the can to the brim with water.
|
Bend the lid closed. Be careful not to spill any of the water. Balance the bottle top on the center of the lid, and balance a pencil on top of that.
Now here's where it gets tricky! You might need someone elso to help with this part. Stand the can and pencil on top of another pencil, and hold it that way while you wrap the ends of the pencils with tape.
|
This is what it looks like when you're done. If you are using ordinary clear tape, use four or five wraps; black tape will only need two or three.
Now carefully stand the whole thing in the freezer, and leave it alone for a few hours.
