Q&A for How to Make an Air Gun

It's quite powerful. If you use the toothpicks, they can puncture the skin and cause bleeding. Always be careful when using the air gun, especially around other people.

You can use any solvent-based glue, like E600, Gorilla Glue, etc. Avoid getting the glue in contact with your skin while it is wet.

Depending on the pressure, it can stay for hours. If the pressure is too high, however, the bottle can burst.

You can try an air pump. Heads of spray bottles actually produce less air than pumps, so I recommend using them instead.

Yes, you could use a water bottle.

Roughly 80 feet to 130 feet for airsoft guns that are meant to be like snipers.

It depends on your gun's model. Most can go 20-50 meters without getting curved, but there are some that can go up to 70 meters.

No, it will be too big.

Generally, about a foot, but it also depends on how you make it and whether you shoot it indoors or outdoors.

Not necessarily. A stronger, higher-quality bottle will take more pressure than a cheap one of the same size. A larger bottle means you need to pump more to achieve the same pressure.

If the barrel is big enough than yes. But the Nerf dart will not fly very far.

It’s not as good as using a hot glue gun but you can use it. The hot glue holds the shape and it holds it together better.
