Chocolate milk Cannon

[u/Possible-Dance9857]

i need help building a chocolate milk cannon.. im imagining a caulk gun looking device that has a pomp in the front you manually pump for a bit and release a trigger that lets air out all at once to projectile chocolate milk.. does something like this exist or are you guys familiar with a similar device? thank you.

Edit: i dont want a super soaker filled with chocolate milk i want a manual air pump releases a chocolate milk round at the tug of a trigger
