You can roll them, play catch with them, or even play fetch with your dog with them.(Larger dogs may choke, my dog is really small and cannot choke on it)

Put Together LED Throwies. It's the same concept as putting together a throwie, except you need no magnet.

Heres the instructable for throwies: LED Throwies

Get one ping pong ball and cut hole in top so that you can fit LED Throwie inside.

Then put throwie inside.

Step 5: Glue it Up

Put hot glue in ball so it keeps throwie in place.

You do not have to fill all the ways just fill so that LED does not move around inside.

any place that i can get a big bag of super cheap ping pong balls ?
dcmania21 (author)  raykholo6 years ago
probly ebay, i got 72 of the ones i used in this instructables on ebay for 15 bucks. They are not real ping pong balls made of cellulose, so u cant make smoke bombs, but they are plastic ones that work well for projects.
of course -- but are they good for actually playing ping pong? (not your instructable, but the original ball...) although it would be cool to be able to play in the dark...

If you don't want to cut the ball in half, you could just drill a hole or cut a slice into the ball and put the LED in that way. Then you only need a little bit of glue to cover the hole and its removable so you can shut it off or change the batteries. I'm thinking this would make a great cat toy. Here's a tip. Make two of these. Put a string through each one so you have a ball on a string in each hand. Turn off the lights and spin them around in the dark. You get a cool streaky effect. But be careful. I did that once with a glow in the dark cat toy. I sneaked up on my wife. It scared her so bad she nearly beat me half to death with a couch pillow. We had only been married a week so she wasn't used to my sick sense of humor. LOL This is great fun. Thanks for posting it.
Too bad there's no on/off switch. The hot glue melted my ping pong ball.

if u just make a peircing in the 'seam' of the ball you can pull the ball apart along the seam and you get a very neat cut straight along the middle. put the LED inside and glue it up witth hot glue!you can the cut off the excess hot glue to make it neater.

i didnt no that, thnks!
No problem
wat if u just cut 1 ball in half &put the LED IN, then super glued the ball back together
It is hard to glue the ping-pong ball together. Think of how thin the ball is.

can u still play ping pong lol
Don't your dogs break them? My Ping-Pong balls are quite delicate, no match for dog teeth.
dcmania21 (author)  Sergeant Crayon7 years ago
well, my dog kinda messes it up, she just makes dents in it.....
Ah, not really a big deal then. I imagined the ball breaking apart (shattering?)
Cool! Too bad it is kind of lumpy. Maybe if there was another way...
dcmania21 (author)  GorillazMiko7 years ago
yea im workin on another way, ill start another better one when i get my new LEDs.
