Water Squirters Update - Electric Pumps and Valves!

Here is an update on the water guns that I featured here previously. For this year's songkran (Thai water throwing festival) I modified one from last year and created some more water guns. 

This first gun is the double barrel squirter that I made last year with the integration of a Nerf Thunderstorm Super Soaker. As the Thunderstorm only produces a small stream, it is not a good primary weapon for any water fight. It is however very useful when combined with the double barrel pipe squirter as it can fire a constant stream from an interchangeable water clip. As it is battery operated and I own two of these Nerf clips, it is very easy to use. 

I made it by unscrewing the pump and nozzle of the Thunderstorm and sawing off the watertight battery pack and integrated button as well as the middle section of the gun, which included the parts where the water clip attaches. These parts (along with some extra tubing) were then all secured to the old squirter with a combination of hot glue, epoxy putty, zip ties and araldite. 

These two water guns work perfectly together, especially when the Super Soaker part is filled with iced water to make up for the low power and amount of water (this is commonplace in Thailand during this festival). It is also fully waterproof, even when forgotten at the bottom of a pool for over half an hour. When the plunger tube is pulled out partially, it can also act as a stock when using the motorised  part.

The second water gun is a variation of the original single barreled version. The difference is that it utilises two valves to suck water through a tube can either be screwed onto a bottle or placed into one of the many plastic tubs or drums that line the street during this time. Like the above squirter, this is an upgrade from the original version as it can be used while on the move if the bottle is put into a small backpack. 

It was made with two valves taken from a small, cheap water gun that was near useless. The end of the nozzle valve was cut off and filed/sanded to make a bigger hole. Another piece from the small water gun was also used to attach the hose and a weight was attached to the other end of the hose to keep it submerged while sucking out of a bucket or tub.
