Water Bottle Cap Trick. Just for Fun.

How to turn a water bottle into an explosion of fun. This little water bottle party trick will make you the most popular guest PLUS provide a distraction so you can eat all the hamburgers.

Today is Friday.  People don’t like Fridays.

They think they are icky because it means the long, boring weekend is ahead of them. They’re going to have to sleep in, stay up late and ignore the growing mound of laundry so they have time to not do laundry.

Every 7 days it’s the same thing over again.

So I have for you something to nix the ick.

I don’t buy bottled water anymore, I haven’t for years and years, but if I come across a bottle or have to buy one for some reason I like to reuse it. The first way I reuse plastic water bottles for is making my homemade fly traps for outside (if you haven’t seen how great this fly trap works you need to read this post).

The second thing I do with them is turn them into a party trick. Sometimes it’s a party for one, with just me in my backyard but still – nothing makes a party for one fun like rocketing the lid off of a water bottle.

You can pull this trick out  poolside, in the office, at the campsite, bar mitzvah or BBQ.

Make the Cap Shoot off a Water Bottle

All you need is a plastic water bottle. 

  • Put the lid on the water bottle but not tightly. Just so that it stays on.
  • Twist the bottom of the water bottle like you’re twisting the link in a sausage.
  • When you can’t twist the bottom anymore, and all the air in the bottle is forced upwards, flick the cap with your thumb*.
  • The cap will shoot off from all the air pressure inside. 

*Make sure the water bottle is pointing away from you, everyone else, windows, glass doors, animals etc. etc. because this thing goes FLYING.

(now you know why as a single woman I have so much laundry)

You are now fully prepared to entertain and delight anyone you come across this weekend. Don’t worry, before you know it, it’ll be Monday again and you’ll be able to ignore the laundry without any guilt.

Author’s Note:    Other life skills I know include “pull my finger”,  “crazy glue – wayyyy faster than stitches” and “smell this”.

    Thanks for giving me something to do during the “potty” stops when I’m cruising with my Corvette Club tomorrow :-)

    Completely OT but I made your rhubarbablob today with fresh peaches from the local orchard. It’s flipping amazing! Blobs should come in lots of flavors, especially peach!

    I have done that on more than one occasion, however you get much better results from your exploding water bottle than I ever have. Kudos

    Hi Karen,

    I don’t seem to be getting your blog anymore. It’s been a few weeks… I miss it! See what you can do. Ta.

  7. Gayla T says:

    Oh, boy! Wait until the kids see this one. I can imagine we’ll have a problem once they figure out how to shoot them at one another but I’ll worry about that later. Wooo Hoooo!

  8. Barbie says:

    I’m totally trying this tomorrow! I have a bunch of empty water bottles!

  9. Amy in StL says:

    I am totally doing that on the next float trip we go on….. we being my coworkers and I.

    HAHA..Just got my son to fix my sound so I could hear this..Love it..you are so cute!! Now I need to go watch your TV show!!!

    I wouldn’t be able to do it. I can’t even open a Pillsbury dough thingy like a normal person because the anticipation of the pop is too much for me! Kind of like waiting next to the toaster.

  12. Karen says:

    Another fun video. Karen, thank you! By the way…Your comment about “we” meaning you the chickens sparked a little memory from my childhood. When my dad was traveling for business, and it was just my mother and I for the evening, she would always say, “It’s just us chickens tonight.”

    I saw someone do the super glue trick on a paper cut and they said it takes the pain out right away. I get paper cuts a lot so think this is a great tip if it really works. But since I read this on internet, it must be true, right? (Your lawyers probably say don’t tell me or us.) Can’t wait to show my grandsons this new trick. My daughter-in-law is still not happy that I taught them to burp the alphabet so I can give her something else to love about me. Oh, and WD40 sprayed on insect stings removes the pain also!

    Love it – what a perfect post for a Monday morning.

    The video is hilarious. And the chicken coop and gate are totally awesome. And your hair looks really cool. And that’s all I have to say.
