Problem is too much or too little water, or not enough pumps of air.

If you put too much water in the rocket, there is not enough air space to provide pressure inside the rocket to expell the water.

If you don't put enough water in, you run out of mass to expell.

Also, sometimes the little pump leaks, and it's hard to pressurize the rocket.

All in all, I would think they would have more luck with the tin-can, pie plate of water, and firecracker technique.
