My brother bert is busy doing a research for school about bottle rockets. We found out that a water cooler bottle (18 litres) also fitted perfectly on our launcher, so why not? This was our first attempt, after which the launcher was broken. But when we've repaired and re-enforced it, it'll be great fun xD. The bottle was filled with water from a ditch btw, and it was all over me, i stell smell like manure!
