About: I like to make things for the internets. I also sell a pretty cool calendar at supamoto.co. You'll like it.

Have some dead tennis balls around the house? With a little bit of cutting you can easily turn one ball into a pair of jar openers. Check it out.

Step 1: Stuff

All you need is a tennis ball and a knife. Any sharp knife will work, but a shorter blade is preferable so that you're less at risk of cutting yourself.

Step 2: Cut!

Take the trusty blade and cut the ball along the seam. Be careful here since you'll be turning the ball around a lot. I made lots of small cuts here. You won't save too much time here by speeding things up anyway.

Step 3: Done!

Presto! A pair of jar openers. The rubber inside grips nicely on metal lids, making it a lot easier to open a jar up.

Step 4: Decorate It

Add a couple of dots and your little jar opener has some more personality! No effect on the effectiveness, but it's more fun.

    this is sooo cool! and i got an idea too if you ever seen those 1 dollar draw liners the rubbery ones you could use those to open a draw or even put under a cutting board so you could add grip so it doesn't slip i haven't found other uses for it so far if anyone does please let me know this thing reminds me a little of the hamster toy i had from McDonald for goosebumps

    What I usually do for a tough jar is get a belt and tighten it over a jar. That works much better then a towel, but this instructables helps me keep my pants off the floor. :P Awesome.

    Do you have to say "wockawockawockawocka" when you're using one?
