Water rocket FAIL
I stacked two sets of spliced bottle using a commercial tornado coupling and another 2L using a home made coupling. I started doing a low pressure pressure test and found the stack was leaking like a sieve. I tracked the leak to the commercial toy coupler. I already have a washer in each end and don't know what else to do. I moved to top bottle down and connected it with my home made one. Well, I won't relay how I made it because the method is obviously flawed. At a mere 30 psi, the top bottle launched. My precious mechanical timer is gone.
