Chemistry

We just came back from the Chemistry Lab at NUS. Over there we were splitted up into pairs of two, and together with a student scientist, we did some exciting experiments. Most of the chemicals that we used were harmful to our skins. So we had to wash our hands immediately after an experiment. My favourite experiment was called the "elephants toothpaste". We used detergent, food colouring and some other chemicals to form a warm soapy paste. The end product looked like a giant toothpaste. I had a fun time at the chemistry lab today.
