Hello, I`m searching for a force bag which is large enough to hold 18 ping pong balls. 9 of these balls are with a random number and the other 9 are forcing balls.
Is there anything on the market? I want to use this for forcing the power ball number in a lottery prediction.

Make it yourself from large transparent Zip-Loc bags from your local grocery store. See more ideas for lottery ball predictions in The Wizards' Journal # 38-05, "PLOTTO", as well as The Wizards' Journal #23-11 - "Bingo/ Lottery Ball Forces"

Thank you for this. I`ll check this out!

Can also look for a Creative Magic large pandora bag. No longer in production, but pop up frequently on used magic sites.

You can try to see if this will work for you, and email this website for the size of their bag.

18 seems you would need a very large bag for ping pong balls. Never seen a super large force bag.

Like this idea, would be interested to see if anyone gets hold of anything suitable?

Use 2 mesh laundry bags that you can get at the large department stores. One inside the other.
