Coke and Mentos

We had a coke and mentos lab competition in chem class today! We could do anything we wanted to it, as long as we don't have anything that'll break school rules.

I had my contraption built all awesome looking and everything- but I had miscalculated the amount of mentos, so the mentos touched the coke before I was even ready! >.<

So, there went all my hope for the extra credit xD
