and it was amazing! In chemistry the professor did a demonstration where he had a balloon that was filled with and 50-50 mixture of hydrogen and oxygen. then he lit a candle that was attached to the end of a long stick and brought the lit candle to the balloon. as soon as the balloon and flame touched there was a huge BOOM and a mini explosion where the balloon was. Imagine the kind of thing you see in tv when a car blows up or a grenade or something like that which creates sort of a fireball. It was just like that but smaller and it felt like the room went dark and all i could see was that explosion. Of course it only lasted about a second (literally).
Looking forward to the rest of the quarter and more :)
