I will definitely put some pics and videos on the site. Thank you for the advice I will make the chamber much smaller - in the 1ft to 18in range -

Thank you...I will definitely take all of those ideas into consideration.
As this being my first Spud Gun i am not going to use propane but may upgrade it to that in the future.

This is my first spud gun and before i build it i want to know if it looks alright.
I will be using a 100k stun gun for ignition and a brush less fan for mixing and cleaning.

1. Should i use more than 1 spark..inside the chamber

2. Is the barrel and chamber a good length
