Then if you go to enquires, you can select what types of tube you need.

yeah i have got it sorry for not speaking

hello

this may seem abit silly to most of you here but my best pyro acomplishment was completed today.
bp rocket.

id: 11mm
walls: 1.5 mm
motor length:6cm
weight:4g
nozzel 3mm

after a 1st atempt today it was a failure because of my lasyness of not using a clay endplug but a paper 1 it flew about 7ft then sore the ent plug shoot out.

2nd attempt was the same dimensions as the 1st but with a clay end plug this time,
as soon as the fuse hit the bp sparks flew out with a most satisfying "woosh".

i was woundering is there anyway i could measure how high my devices reach without using little probes on them?

i have gone off the idea of chlorate/ sulphur rockets but i am now gonna use bp in my rockets.
what dimensions should i use for my 1st rocket?

i dont want bits of me missing please
so its not possible for me to use this as a rocket fuel?
