Today was filled with awesome elephant toothpaste, film canister rockets, balancing balls on ropes, magic sand, and an experiment that failed.The fist super hard thing we did was balance a ball on a rope to get it in a bucket.We did this by folding the ropes and holding it really tight that so the ball could roll on what was a "rope ramp" into a bucket.It was really difficult getting the balls into the bucket because the balls kept falling off.After that challenging activity we went inside to do an expiriment called think ink. We mixed water and various powders and just waited for along time but it did nothing. It didn't work because it was supposed to turn black but it remained clear. Then after that disappointment we made elephant toothpaste which was awesome.To make it we combinded hydrogen peroxide with dish soap, food coloring and to make it react potassium iodide. The mixure bubbled and oozed out of the top of the beaker. It was so awesome!!!!!
Then we played with hydrophobic sand. Hydrophobic sand is sand that never gets wet.Its really cool to put in water and pour the water out and feel that it isn't wet. We played with that for a while then went on to film canister rockets. To make them we filled canisters with water and Alcester so when you put the lid on the they would explode. They went really high and to make alot more fun we glued magnets to the top and Alcester tablets to the bottom and put them onto a metal tray so that when you turned them over they all would explode.It didnt really work that well but A for effort. Cant wait untill tomorrow because it will be an awesome last day.
