Science

Today in science we did four experiments. My favourite one was the one called fire extinguisher. We used a plastic piece of tube, some baking soda, some vinegar and a coke or pepsi bottle with a hole in the lid. We poked the piece of tube in through the lid, then made sure in was in properly by sealing it with blu-tack. We poured vinegar into the bottle, and then quickly added baking soda. When we sealed the lid, we put a finger over the end of the tube that was outside of the bottle, and pointed it at a candle that had been lit. My group was the only group that sucessfully blew out the candle, and it was a lot of fun, along with the other three experiments.
