  • I combined instructions from these two different sources to create my water rocket launcher. Also, all of my 2 liter bottles had an opening which was to small to fit the 1/2” PVC pipe. So, I warmed the neck of the 2 liter bottle in boiling water and fitted it over the 1/2” PVC pipe to stretch the opening to fit. 😀
