More Science Experiments by Rus

Hi. I am Rus. I am going to talk about the experiments. There is one that I want to tell you about first. We put a pin in a bowl of water with toilet paper. The surface tension made the pin float. The molecules in the water stay together and that blanket that they make makes the pin float. There was another experiment. We made something that is neither a solid or a liquid called non-Newtonian fluid. It turns to a solid when pressure is put against it. We made this with corn starch and water. The last one we made is sorbet. We put in ice and salt water in one bag and orange juice in the bag inside the other bag. Why use salt? It lowers the freezing temperature so that the juice would turn into sorbet. Then we shook it. Then we had sorbet.
