Day 123

Chemistry day, really cool. We drove out to the University of Puerto Rico to visit a friend of Betsy's who is a chemistry teacher. He did all sorts of cool stuff. We burned ethanol gas, played with dry ice, and he poured a tank of liquid nitrogen into a bucket of hot water. A few of the kids laid down on the ground and you could hardly see them through the through the cloud. Saúl, Gaby, and Kioney came to school today even though they were sick. Which is good because it would have been really sad if they missed chem day.
