Caulk Gun Uses

About: I like inventing, experimenting, rockets, film making, and more! I consider myself a teenaged genius. I feel that with enough time I could build anything.

This is a collection of caulk gun uses I discovered.  I got this caulk gun at Big Lots for about $2.50.  I thought that was a good deal for something I had no idea what I was getting it  for.  My original intention was to use it for a spoof movie I have been working on.  While I was goofing around with it I came up with some more uses for it.

Step 1: Squirts!

I happened to have a spare condiment squirter lying around and decided to put it in my caulk gun.  You can use it for squirting ketchup or fill it with water and squirt people with it.  Now be warned, I never tried these things but I do know it will break the bottle if you aren't careful.

Step 2: Useless Flashlight Holder

I tried putting a flashlight in the gun and it held it pretty well.  I would suggest using a small flashlight.  Ironically this completely voids the purpose of a small flashlight.

Step 3: Salt

I put a small salt shaker in the caulk gun.  I love salt.

Step 4: CAULK!!!!

I will put up more stuff for the caulk gun uses as I find them.
If you find any ideas for uses with a caulk gun let me know in the comments.

    Nice! I did this stuff too :P Keep trying, be safe, and ignore those that try to put you down for being curious. Have you considered replacing the metal stick with some all thread? It works great! I made a ratcheting vacuum pump with this. You can also reverse my tutorial and use the gun to build up pressure, but this can kill you... so have an adult help and make sure that you use HIGH pressure PVC to be safe. You can make a Gargantuan pump-action pellet gun with this! >.< It takes a while to reset, but it's absolutely hilarious! You can fire bigger objects than BBs... just don't point the 'suped up pellet gun at your friends. Get some gun safety advice. I got my advice from my local NRA cause I didn't have a Dad and my mom didn't know how to use guns.

    OH! Also what does that weird silver bit of the caulk gun do? It's in the upper right corner of the gun in the pic. Ghar! I can't explain it. Here's a picture. 

    What does the thing I circled do?
    I haven't seen that before.

    When you press and hold the tab it lets you pull the lever out, and when you hold it and the trigger down, you can push it back in.


    huh... that's... AWESOME! I'm going to use this type of gun in my future hand pump vacuums! Mega Thanks!
