I love these and am anxious to make a bunch with the zip-tie handles, but the weight of the coins would make the ball come loose from the zip tie.

What keeps the zip ties from sliding back out of the cuts you made in the ball? Evidently, the ends are not threaded and 'zipped' - correct?

Thanks, -Sprout

They are zipped on the inside. You cut the holes from the outside, but you feed the zip tie from the inside out, then back in and zip it.

how do u get the money out srry i know it sounds kindi stupid?

papris made it!(author)2011-02-14

When you squeeze it really hard, the mouth opens wide enough to get them out. At least, that's what I did... There might be an easier way.

wow, you're video is epic and I think that's the most original idea of saving money I've seen. Simple yet effective =)

This is perfect as a dog treat holder; I fill mine with small kibble (cat food, actually) and keep it in my jacket pocket. No more crushed kibble dust in the bottom of my pocket. I can easily squeeze it open to dispense a couple treats. I may hang it on my dog's leash next to the doo-bag holder thereby taking care of both dog input and dog output during our walks.
It also serves as sort of a poor man's Kong toy. My dog got hold of the "Kibble Muncher" and had a blast trying to get the treats out; he seemed to be performing his own Bollywood number. I wouldn't want to leave him alone with it due to safety concerns: it would not be fun to get one's tongue caught in the Muncher's mouth!
Excellent Instructable for a multi-purposed Muncher. Thanks!

Thanks Puzzledd!! And thanks so much for the patch, my first one! I'll send the kudos to the rest of the group :-). Glad to hear we made your morning, fun to know that the video has positively effected someone's day!

BRILLIANT!! Simple project and fun result...

Every 'ible' should end with a Bollywood dance scene!!

astrong0 made it!(author)2010-11-26 do you get it out? because i don't think that the "hammer" method would work here.

Adder+Twist made it!(author)2010-11-26

According to the author, "Squeeze the ball so the slot opens up and shake, or just tip and pour while squeezing. Easy to get the money it, a little tricker to get it out, which makes it a great way to SAVE money.. not spend it :-). You can also hide things in it that you don't want people to find. If you are desperate to get your money out and still have trouble, you could always just cut the slot bigger."

I'd also like to say that you can rip the tennis ball by sticking your fingers in the slot and pulling hard.

In the video...

Did I imagine it, or did the munchers glow?

Did you feed them throwies?

sharon13m made it!(author)2010-11-22

Not sure what a throwie is exactly..but I don't think so? The Money Munchers look to be glowing.. but those are actually battery operated candles glowing... to make dancing in the dark more fun to watch.
