Hmmm, good point. Would you personally trust something like this?

Cool idea and pun =p

Like this one?

I'm not sure how these operate. Are these closed when no power is applied and open when power is applied. Or does applying power just toggle the valve state(open/close) with a single press?

What do you think about this setup for the trigger?

Handle: $16

Trigger: $10

Other parts on my list so far:

20 lbTank: $140

Spout 6" diameter: $23 (Drill holes in sides to relief pressure and drill bottom for hose fitting)

Hose: $15

Need fittings

add LEDs (optional or could do later)

Subtotal: ~ $210-$250 to complete project

Current plan:

Mount valve on top of Handle. Make battery operated. Need battery mount. Hose from tank to valve. Valve to quick release fitting. Quick release to mounted fitting. Mounted fitting drilled and mounted to bottom of spout(cup). Dill holes in sides of spout.

Thoughts? and Thanks!
