Today for dicovery Friday Mrs Hickford got a hotwater bottle, a tube and some water. Then she connected the tube to the hotwater bottle and told Indi to stand on the hotwater bottle. Next Mrs Hickford poured a jug of water down the tube and held the it above her head, slowly Indi started to rise off the ground beacuse the hotwater bottle was filling up and getting bigger. The resion this works is beacuse the presure of gravity is stronger the higher you lift the the tube the more downward presure than your weight.
