Prank Water Gun - Non-Electric Pump - GIF Inside

This is the all new April Fools Day Prank Water Gun with a non-electric pump. 

 

Description:

A deceptive 3D-printed prank water gun designed to turn the joke on the user. It appears to be a normal front-shooting water blaster, but when the main trigger is pulled, it secretly sprays backward—so the person holding it gets soaked instead. A hidden secondary trigger on the back allows the real forward shot, making it the perfect trick for catching unsuspecting users off guard.

 

How it works:

When the main/normal trigger is pulled instead of shooting at your enemies like you'd think it actually shoots right back at you through a hidden nozzle in the pistol's sight. But if you're the lucky one whos printing the water gun you get to know the secret trigger located on the back of the gun which actually shoots your targets.

 

The Pump:

When the trigger is pressed it pushes an air tight valve down displacing the water inside the main chamber causing water to shoot out the main nozzle. 

 

BUT why doesn't it shoot water out the other end as well?

This would be because of these orange tic tac lookin guys that sit inside the valves. They act as locks for the valves that float along with gravity.  This means that bottom valve cant push water out because when it tries it gets blocked by the lock but when it sucks water in it can move the lock out of the way allowing water to pass and vise versa for the top valve. Therefore if you flipped the gun upside down it would actually suck in water from the nozzle and shoot it from the intake.

Boost MeI am currently attempting to my own version the pump 3d printable as well but am running into some major issues with it (Primarily the spring and the air tight seal which moves the water). If you would like to see that become reality please support this project by leaving a boost and like. TYSM :) 

Assembly:

Step 1:

Once the pumps are removed from each gun pull out the trigger as shown.

Step 2

Insert pump into main compartment (it may be hard to get pump fully click into place so for extra assistance use the back side of an exacto knife or tweezers). Then reinsert the trigger back into place.

Step 3: 

Insert the second pump into the upper compartment with the spurting tube rotated 180 degrees. 

Step 4:

Insert nozzle head into the gun end as shown. 

Step 5:

Put the main pump nozzle sticking out of water cap. Then slide the the two pieces together to connect them. 

Step 6:

With tweezers insert the main pump nozzle into place as shown. 

Step 7: 

Reinsert the trigger back into place.

Step 8:

Insert the secondary trigger as shown.

Step 9:

Insert Cap as shown. 

That's all folks. Now go have fun and don't get anybody too pissed off.
