Picture of How to make a heavy duct tape tennis ball (Pitcher's Ball)
Hey everyone, this is my first instructable. Here I will be showing you how to make a Pitcher's Ball (duct tape tennis ball).

For this you will need:
-Tennis Ball
-Duct tape
-A lot of small heavy objects (coins-- pennies are the best, stones, bolts, etc)
-Knife or scissors

Why would you want to do this?
To freak out a friend by tossing them the ball and watch them fail at catching the heavy ball because they think it is light (they haven't felt it).

Shot put

Working on pitching or throwing and catching-- if you practice with a heavy ball, and you become good with it, then when you switch back to using a normal ball, it is very easy to catch and throw.

Random Fun-- Just tossing it back and forth with a friend

NOTE-- I am not responsible for any damages or injuries caused by this. It is heavy and can be dangerous if thrown at someone. This should be common sense. Build and use at your own risk!

Step 1: Find the coins

1. Sort your coins and make a pile of all of your pennies (or whatever invaluable coin you use)

I'm sure that everyone has a bunch of extra change lying around somewhere, so find that and sort through it to find the pennies (pennies are the best because they are small and cheap). NOTE: You will not get the coins that you use for this project back unless you destroy the final project (very difficult). Because of this I highly recommend using pennies because they are fairly invaluable.

If you are not using coins then make sure that the objects are fairly small and that you have an abundant supply of them.

Step 2: Cutting the tennis ball

For the tennis ball i recommend using the dirtiest one you have (NOTE: you will not get it back unless you destroy the final project).

Then using a knife or even a pair of scissors, (carefully) cut a small slit in the tennis ball (big enough to put pennies in-- maybe a inch or so long).

After cutting the tennis ball you should be able to squeeze the tennis ball so the hole will get larger.

Step 3: Putting the coins in the tennis ball

While squeezing the tennis ball start putting your coins in. You can decide how many coins to put in by frequently feeling the weight of the ball. However, with less coins in it, they will shake and move around a lot more.

What I did was fill up the whole ball with coins to make it extra heavy.

Step 4: Putting the tape on the tennis ball

After you have the desired weight, tape over the ball with duct tape. Cover all of the ball with about 5-7 layers of duct tape. This ensures that the ball will not break leak coins. If the tape gets torn somehow later, just out more over it.

Note-- It is nearly impossible to take the tape off and get your coins out after this step.

Step 5: Enjoy!

Test the by throwing it up and down (outside of course). Or play with it with a friend.

This is very simple to make and takes only about 5-10 minutes (not including sorting through your money to find the right coins).

These last forever and can be repaired very easily which leads me to me motto:
"Duct tape can fix everything"

Very cool. If only I could juggle, I would make three of them. Neat!

Where did you get that knife from? I think i have the same one.

It's a teeny medicine ball! I love it.
Sorry, didn't read step 1.
To get the coins out, couldn't you just cut straight through the tape and tennis ball?
Four stars for the Papaya ible: About a year or so ago I found what looked to be a regular tennis ball in one of my mom's junk drawers. But when I tried to pick it up I nearly gave myself a hisnia. It weighs like 3 pounds cuz it's full of lead. I asked her about it. She said it was the, "Papaya". She told me she used to work at a bar and when customers would start getting "grabby" she would ask em if they wanted to go into the office and see her juggle. She used two normal tennis balls and the heavy one. She'd juggle for a bit then throw one of the light ones real high and bounce it off of her head and continue on juggling. She'd do that a couple times and then throw the heavy one up and say, "Your turn" and then "Papaya!" (Whatever that means) She's just nutty like that.

Trying this on a golf ball, My idea is to put pennies in the wrapping... will tell you how it goes.

Suprisingly nice.

Now combining this idea with the rubber band ball idea!
mehasakoolname (author)  Someguy445 years ago
 Good luck! One fun thing to do with this is to throw the ball to someone who doesn't know how heavy it is and watch their reaction.

 Actually, it costs about one billion dollars in tax-payer money to mint pennies every year. The point: they're not as cheap as you think they are.
mehasakoolname (author)  PastTheVoid5 years ago
 We're not worrying about the government or tax dollars right now. This thing only costs a few dollars, which can't even buy you much nowadays.

I don't even play baseball but I still made one.You can play some epic games of catch with this ball. 
mehasakoolname (author)  tabler10105 years ago
 Yeah you really can, but throwing overhand you can injure your arm, so be careful.
Just a question... about how heavy is this thing? i would build it, but im not sure if it will be heavy enough to be worth building. this is assuming that i did it like you and filled it to the brim with U.S. pennies.
mehasakoolname (author)  PyroManiac965 years ago
 Umm it's fairly heavy, enough that after throwing it for a while (overhand) your arm gets sore. Probably just a few pounds.
keyguy136 years ago
I think you should screw some spikes into it (large ones that aren't sharp and then cover it with epoxy. That would look cool.
mehasakoolname (author)  keyguy135 years ago
 I'm not trying to kill people.
woodnt rice, or pebbles woorks just as cgood, or smash a lot of rocks n collect all of hte thick small n thin shattered peices

 That would work, but I just used pennies because they are heavier.
sand wood be good

you forgot the other great motto: "if you can't fix it with a hammer, you've got an electrical problem."

thats a good idea, Ill have to do this with something other than pennies, though, im cheap, lol
mehasakoolname (author)  scott!6 years ago
haha try rocks or sand, that's what some other people tried.
Halopwner856 years ago
this may sound stupid but would concrete be to heavy what about sand?
mehasakoolname (author)  Halopwner856 years ago
Concrete would probably make the ball to solid and heavy. I would just be like picking up a rock with concrete. Sand is a good idea though!
lol ok.

HokieBird046 years ago
It's a little heavy for my needs, but it was fun enough to get me to create an account for the purpose of thanking you. So, thanks!
mehasakoolname (author)  HokieBird046 years ago
Wow, that's probably the best feedback that have ever gotten from someone. I'm glad it worked out!
reesea6 years ago
i used a mix of .177 caliber bbs and pennies. it is from my exp. the heaviest. the bbs fill out the spaces that the pennies leave. try it
this is what my spanish teacher throws at us when we screw around... heh
You could use anything really, even small stones or nuts and bolts you don't need rather than money, I wouldn't dare make on in my house, there's a hole in the wall from throwing stuff about for fun...
mehasakoolname (author)  killerjackalope6 years ago
I guess other small objects would work, I just edited it a bit. Thanks for the tip!
No worries, just saves you a few pennies....
