Actually, it was lead free solder. Personally I am not a fan of inhaling lead fumes. And I don't have a good way to ventilate my room well so, lead free it is.

I have that same issue. Except mine is resolved. Your need an internal launch right. Well I used heavy latex balloons, cut a small hole in the end, insert it in nozzle put balloon nozzle on pump and fill it up. Stop pumping and away she goes! :idea:

That sounds a little bit like that way that the launcher from Anti Gravity Research works. Only they use a small rubber nipple and a small diameter hole in their bottle cap. The principle sounds the same.

Hey I know this might be a bit, but if you know anything about Anti gravity's staging can you clear me up on it. If you have pics that would be great. Also, what glue can I use to splice bottles. I have been using JB Weld Clear (3240 psi) and in cold weather the bottles blow apart at 50 psi. Maybe you could help me a bit. Also what king of altimer can I buy. Is the AltimeterOne good? :D

You should use PL Premium Construction Adhesive.

Complete instructions for splicing bottles can be seen here:
