Step 11: Put Stuff Inside

Tennis balls are hollow and easy to cut into. This makes them perfect vehicles for intra-office correspondence, hiding precious valuables at the gym, or any other activity that might require ballistic containment.

Just cut a slit into the side of the tennis ball. Cram in your message. Hurl it to your intended recipient.


Cut a slit into the side of the tennis ball. Cram in your cash. Stuff it under some dirty socks in your gym bag next to the Tinactin.

Door knob used to hit a wood post in my basement--drywall screw and tennis ball solution!
Awesome! I can't believe I missed this one. I've seen this done with the tennis ball placed over the doorknob, but this seems a lot better. <br /><br />For posting another use and a pic, have 3 months of pro membership.
<p>Wrap a ball with each corner of a tarpaulin : the bulge thus made will allow you to tie the latter very taut without the risk of seeing the lines slip from the tarpaulin's corner as it happens too often. You can use soft rocks too &hellip;</p>
<p>Your description is unclear. Also, I have never heard of a &quot;soft rock&quot;.</p>
<p>I understood perfectly. I thought that soft rock was a bit of homur. lol.</p>
Tie the corner of the tarp around the tennis ball then loop a rope or bungee around the &quot;neck&quot; (if you picture the tennis ball bulge as the head) and use rope or bungee to tie the tarp to whatever. <br>One can only assume he meant smooth rock.
Pro membership? Thanks! I appreciate your kindness.
<p>When I was younger (in my teens) my older brother and I were rough on the dry wall behind doors. My dad would a version of this on those doors.. I won't go into the punishment we got on top of having to fix the dry wall. Anywho, he would cut an X on the back and put the tennis ball over the door handle. He also did the same to put over his trailer hitch to protect it and make it more visable. </p>
Put the ball in a long sock or stocking, throw it over your shoulder, and you can move it around while rolling against a wall. It doesn't drop every time you move.
<p>Did someone tell you that there are actually 11 uses? Keep up the work.</p>
<p>These are some pretty clever ideas. Some of these will come in handy in the RV. Thanks for sharing these!</p>
<p>Had some inexpensive coat hooks in my closet that made my clothes have little dents so I added Tennis Balls over the hook tips....</p>
<p>While I enjoy the info, I hate the format of having to hit 'next' over and over and waiting for all the ads to display before being able to read the content. I think all the info could have been contained in an article format, or just a simple list. I'm not even making it to the end of this - NEXT!</p>
<p>there is a button marked &quot;SHOW ALL&quot; <br><br>click it and all the steps are in one page... the full instructable always takes more time to load than just a fraction of it so websites break up content to not lose the impatient azz holes<br><br>after all, pressing the &quot;show all&quot; button might take a whole three seconds for the page to load</p>
<p>If you are worried about ads use ad block it works great.</p>
<p>@DJTX - right next to the &quot;NEXT&quot; button is a &quot;View All Steps&quot; button. At least there is on my computer. It allows you to view all the steps in one one page. </p>
<p>They are also great for writing your phone number on - in case you meet eyes with someone attractive while out for a drive. Just get them to roll down their window and give it a throw! (It's a real win if you add a compliment)</p>
<p>And who ever knew these yokes'd be so versatile??? I'm intrigued though. As an amateur photographer learning a new skill I like anything that'll improve a shot and the idea of a counterweight camera mount is genius, but where it says no attach to tripod,, any ideas on how best to do that?</p>
<p>Put one over your (well greased) tow-hook when you're not hauling a trailer.</p>
<p>My wife, kids, and neighbors seem to do a good job cleaning the hitch ball lube off within mere minutes of me parking within 10 feet of a sidewalk or street. And they still act surprised and angry every time they walk into it, climb on it, or grab onto it. (Why, oh, why?) This method ensures that a fresh coat of grease is applied regularly. And it keeps Reese in business.</p>
<p>Reese? you use peanut butter and chocolate?</p>
<p>Great 'ible! I can decide which was funnier, the comments or the instructions!! LOL!!!!!!!!!!!!!!!!!!!!!!!!!!!</p>
As far as putting tennis balls in the dryer, Im worried about how they make the clothes smell. Tennis balls don't have a nice scent to begin with, then heat them up... doesn't sound very good. Can anyone put my fears to rest?
<p>I use tennis balls in the dryer all the time and never have had a bad smell. </p>
<p>You forgot that a half-opened tennis ball makes a GREAT addition to the stem of your skiff or punt, keeping the bow from shattering against a floating dock. Tennis fender!</p>
<p>Anti bed squeaker</p>
<p>your comment was almost as funny as your NAME <strong>x^D</strong></p>
<p>nobel prize!</p>
Find a way to put them on top of the gfs bed posts to keep them from smacking the wall ... and you might have a sellable idea...;p
<p>Hey apparantly you can use them to play tennis with too!! Who knew? Cool I'ble</p>
For better hamstring flexibility, you can roll a tennis ball under your foot for about 10 minutes a day. My yoga instructor told me this due to my lack of flexibility. She explained that this particular muscle group ran from the bottom of our feet to our opposite eyebrow.....left foot-right eyebrow and visa versa. Needles to say, with the help of rolling a tennis ball (and proper stretching) I can touch my toes.
<p>So when you roll it under your left foot, your right eye starts to blink?</p>
<p>OMG! This comment has me seriously Laughing. Best thing I heard so far today. What a visual. LOL </p><p>Even funnier, people will actually believe that. LOL</p>
Might help with flexibility but your yoga instructor doesn't know much about anatomy.
Absolutely, and it's also good when your sciatic nerves acts up ,you roll it in circles around the dimples above your butt.
<p>oh wow will have to try that one Have been suffering from sciatica for couple of months never thought of that</p>
<p>OMG, too too smart </p>
<p>Oh if you have tile floors and you have a big table, in a room that <br>needs a good scrubbing, lift the corners one at a time, put on a <br>rubber ball foot, move the table clean the floor, push it back remove <br>the tennis balls.</p>
<p>How do you lift a 4 leg table one leg at a time. That would make a wonderful &quot;instructable&quot; in of it's self</p>
1 leg at a time is usually easy slipping something under it with a foot. But for heavier tables I have squatted under the table using legs and back lifted the end of the table, (think standing up), then slipped stuff under the leg to move it or to straighten a leg then tightened up the 1/4 20 nuts to secure it better. <br><br>It sounds like Conan the Barbarian brute force, but it really isn't. If you have a liver and a fulcrum you could do that as well, and again place the slider under it. <br><br>Don't whine, try it, you'l like it. You won't drop a nut or crack the back. If you have really bad back or are more ancient then me (I gotta gum me food), well don't try it, call movers.<br><br>After you learn to use the brain more in way you never do , this stuff becomes second nature. I am not flaming you I am not calling you dumb. What I am suggesting is people need to look at problems differently. <br><br>if it were a really heavy table, like say a solder wave machine or soapstone lab bench, I would put a car jack on a board under the table then another on the top and jack up 1-2 legs at a time then put the glides then do the others. <br><br>One day I will make an instructable. then I can answer even more questions. <br><br>have a great day.
<p>And was that only one leg. Every time I lift a table or cabinet that has 4 legs two always lift. I want to know how to lift only one.</p>
<p>well one side goes highre so there you go. If you have a helper then they can do 2 balls at once.</p><p>Oh and the liver is not what gets mangled, the spinal column gets the fun. Trust me I used to pull big wire 3 phase 4 wire 7 pounds per foot. through 4 inch pipe with a machine and 6 guys. We smoked one pulling machine after it tore itself from the concrete floor. 1/4 double expansion bolts failed.... </p><p>Ah the goode olde dayes, when al;l my joints worked. Liver is fine, but those pesky joints......</p><p>MONGO LIKE , (this instructable), !!</p>
<p>Seriously, Dude, if you DON'T have a liver, let someone else do the lifting.</p>
<p>I think I'd prefer to use a lever, might be a little messy and bloody if I use my liver! LOL!</p>
<p>I don't know who the writer is but, I think I want this person to write my life story!!! very amusing read!</p>
