Today we did science, with water. We stand on a hot water bottle, you need a hot water bottle some wood and a jug, with half of it filled with water, and you need tube with a smaller jug. Connect the tube with the smaller jug, and connect the tube to the hot water bottle then put the wood pieces on the bottom and on top, and make sure they have holes in them grab rope and tie it. We learn’t that how you get taller is from the iron plates, the gravity comes from the iron plates when they spin around. So the water gets forced down, and the air comes up through the water, making the air come up to the top. Then how we get shorter, is cause the air comes out due to the shorter you get, it gets compressed in between the water bottle and water. We ended up lifting 3 girls and 4 boys.
