Snowball fights are fun but nobody wants to lose. Enter the Snowthrower.
It is a ball-pump powered, shotgun style, snow flamethrower that shoots bursts of snow through holes in the front of the gun.
The Snowthrower can also be adapted to shoot airsoft pellets, although it doesn't shoot them far, it does sting on bare skin.
Now lets get building.
Step 1: Gather Parts
Parts and tools list.
>2, 9 inch pieces of 3/4 inch pvc pipe
>1, 5 inch piece of 3/4 inch pvc pipe
>1, 3 inch piece of 3/4 inch pvc pipe
>2, 3/4 inch pvc right angle elbows
>2, 3/4 inch end caps
>1, pen tube
>miniature ball pump
>1, schrader valve
>1 circular lego(not picture)
>hot glue gun
Step 2: Prepare Valve, Snow Guard, and Barrel.
Start by hot-glueing the circular lego deep into one of the pipe elbows. The lego is acting as a gaurd to keep the snow from filling the rest of the gun and getting into your pump. The picture will best describe this.
Next, get your schrader valve and remove the valve core from the tube. Then, drill a hole in one of the end caps and insert the valve so that it is poking out the front and hot-glue in place
Finally, get another end cap and drill another hole in that one. Make sure that the hole is just big enough for the pen tube to slide easily in and out. Hot- glue the tube so that pretty much all of it is sticking out the front of the end cap. Hot-glue the tube on just the outside or it might block airsoft pellets or snow from escaping out the front.
Step 3: Assemble Gun Body
Begin assembling your gun's pvc pieces. Start with the 3" piece by inserting both ends into the two pipe elbows. Make sure that the elbow with the lego in it is the one that will go into the barrel assembly. Make this assembly by inserting one 9" piece into the end cap that has the pen tube on it. Slide this into the elbow that has the lego in it. Next, take the end cap that has a valve in it, put it into the 5" pvc pipe. Slide that pipe section into the other pipe elbow. Then screw the ball pump onto the valve and tape the other 9" pipe onto the pump, and the 5" tube. This will keep the pump from bending when you pump it. Again, refer to the pictures. YAY!!! You are done!!!
Step 4: Shooting
Take the 9" pipe off the gun assembly, (Remember, keep the end cap on!), and fill it with either airsoft pellets or snow. (I call them cartridges and cover the ends with duct tape for storage.) I made several different cartridges that have different effects when shot. Sadly, because I live in Arkansas, there is very little snow, so in replacement I used flour. The effect is pretty much the same, although I would suggest using as powdery snow as possible. Airsoft pellets shoot about 20 feet while the "snow" shoots 4 or 5 feet but in a big cloud that blinds and stuns your enemy so you can nail them with whatever other weapon you choose.
Have fun dominating your competition!!
