Home made water rockets

[hash tag]

Has anyone ever considered making their own rocket? By accident I found the National physical labatory yesterday.
Looking further, I found a Water rocket challenge.
This is scripted, but very engaging

I remember doing it - schrader valve in the bottle cap, and a car pump. Could get a 2l PET bottle right over the house...

My uncle bought me a water-powered rocket for a birthday present as a kid and it didn't fucking work.
