Build a launch ready rocket usin' only household items - paper, drinkin' straws, tape, glue, etc - and estes model rocket engines. Ya scallywag! Video tape what you have built and make a video response t' this one. We used Estes A10-3T engines because they are small and we thought they would work better than t' larger size engines. Avast! They have a charge at t' end o' their flight time, so if t' rocket comes down early be sure t' wait for t' pop before you pick it up! Some o' our rockets flew better than others, but all o' them made it off t' ground. Ahoy! Good luck with your rocket!
