Are Spud Guns Legal?

Of course their legal as sated so by the U. S. Government. Otherwise I'd probably be in jail by now.  Please read the Legal Stuff and Disclaimer under my Spudgun Page.

Why doesn't my BBQ igniter work ?

Either (1) your two contacts are wet or (2) the contacts are too far apart.

Why doesn't my solenoid valve work ?

Most solenoid valves require a 20 PSI minimum working pressure.  A lot of the time people make the mistake of mounting the valve backwards.  Always make sure the bleed screw is properly secured.

How does your hovercraft work ?

This is clearly described on my main hovercraft page.

Could you use your cannons for paintball?

Technically, the answer is yes.  Most of my cannons, given the right barrel could be used for paintball.  However legally, the answer is no.  At most paintball fields, the have a maximum fps (foot per second) muzzle  velocity limit.  These cannons could be used for paintball only if the muzzle velocity was lowered to the limit. As an effect, the range and accuracy is going to suffer.
