Have you ever tried to make a paper clip float on water? We tried in Room 13 and at first we were unsuccessful. Then Mr. Healy showed us how to make the paper clips float!
Step 1: Fill a jug with water
Step 2: Get a paper clip and some tissue
Step 3: Gently place the paper clip on the tissue and then on the surface of the water.
Step 4: Using a pencil, carefully push the tissue away so the paper clip is floating alone!
What happens? The paper clip floats!
Why does this happen? It happens because of something called surface tension. It means there is a skin on the water that means the water molecules cling on tightly. This is also how some insects can "walk" on water!n” to walk across the surface of a stream.
