In Primary Prep we have been learning about sinking and floating. Did you know that an egg will float in salt water but sink in fresh water? We slowly added salt to fresh water until our eggs floated at the top. Then we added more fresh water until the egg floated in the middle.
After our salt water and fresh water experiment, we made bouncy eggs. We put our eggs in a cup, added vinegar and then added food colouring. We then put them in a cupboard until the next day. When we checked the next day, we decided that we should wait one more day because they were not quite bouncy enough. The next morning we couldn’t wait to play with our bouncy eggs. Three of our eggs accidentally broke, but the rest were bouncy. If you pop your bouncy eggs, they look a bit crazy, and we don’t recommend eating them either!
