So the more the thrust would give me a greater height ? The faster the water comes out would give a greater height ? than that of something a little more constant?

i think that a fraction of a difference in the radius could make a difference? thats me assuming yet i know they say dont assume.. like i am saying 3/4 is the lip of the bottle to 1/2 or 5/8

i have heated a few of the bottles and well i cant get it to shape evenly giving me one side with more weight than the other also it throws off the amount of water thats going.

I use a heat gun and a pump to make sure the pressure is outwards rather than in wards when heated.
