Don’t you like having a thousand of something? Yeah, same here. We recommend this bag of 1,000 (we did the math, that's only 2.4 cents per marble) glass cat’s eye marbles in a rainbow of colors. Called Peewees in the marble world, they’re 12mm dia, which is 0.47”, which is like a really big pea, or a really small garbanzo bean. Play mini-marbles, or make clay cats and use the marbles for eyes, or just keep them in a big bowl for their prettiness factor.

Newtonian demonstrator for science teachers. Mindless play for the rest of us. These are shiny, nicely balanced, high-performance examples of the classic Newton's Cradle - a ball on one end of a row of (5) suspended, barely touching balls swings into the others, and the ball at the opposite end reacts to the collision. The 11/16" dia balls in the small version (all-metal frame 6-1/2" high x 4" x 4-1/4") will collide about 30 times. The 7/8" dia balls in the large version (metal frame 5-1/4" high x 4" x 6", with a wooden base) will collide about 100 times. Awesome. Even more awesome that we paid someone to count the bounces just for you! (Unpacking note: Less awesome if you just yank it out by the suspension lines and pull a couple of balls loose. Be gentle.)

And we say that with a history of silly that’s virtually unmatched. You slip on this pair of lens-less glasses with the tiny bucket and ball on a string attached, and try, while looking like a demented chipmunk, to swing the little ball on its cord and drop it into the cup. In red and blue plastic, you will be filmed on a smart phone, it will be put on social media, and you will be famous for it for the rest of your life. Best to order a couple so you’re not alone.

It's a toy! It's a scientific demonstration! Drop the 1" ball with a straw attached and watch the outer rocket straw launch. The farther you drop it, the higher the launch, which is the fun version of Newton's Third Law of Motion.  And we give you (2) rocket straws on account of we know you're going to lose one.

You take the Moo Popper, an open-mouthed 6" tall rubber Holstein, stick one of the (6) 1-1/8" dia chartreuse (or grass-colored?) foam balls in its mouth, give its bovine belly a good squeeze and it expels the ball across the room. Harder you squeeze, farther it flies. Impressive ballistics, good clean fun and an educational look at dairy farming practices all at the same time. Sorry, no fully automatic cows are available.

Perfectly suitable for all your non-professional ping-pong-ball applications. These guys are white-ish, with a visible seam, and are 37mm in dia, as opposed to the standard 40mm or the former standard 38mm professional ping-pong balls. Priced so you can buy enough to do any number of clever things with them.

Squeeze your stress away with this squishy ball in bubble gum pink, with the added aroma of bubble gum. Like the real thing, your bubble gum stress ball may lose its flavor after a while, but your stress will be gone, too. And when it returns, just squeeze that ball again.

Don’t confuse this 2-1/4" dia “Pinky” hi-bounce latex ball with that pink ball used in New York since time immemorial for stickball, stoop ball (pinners in Chicago) and other venerable street games just because it looks and acts the same.

They’re festive because they have multicolored tiny stars suspended inside of them, so bouncing them is extra fun. In a golden-ish clear color, they measure 1-1/4” dia. You'll receive a bag of (12) balls, because a couple will probably disappear to the same place those missing socks have gone.

Not quite super-ball category, but plenty bouncy. We’ll send you (2) different orbs ranging from see-through with a bunch of glittery, multicolored stars inside to covered with swirled colors reminiscent of Munch’s The Scream or pink and yellow like a tropical sunset. All of which are super by themselves. Measures 1-3/8" dia.

Together again and not available in any store we've ever heard of. Our party favors set includes an improbable 2" dia squishy egg with yolk, a similarly sized squooshy tomato, a 3" long high-top gym shoe-key chain, and a nice set of joke partially rotted upper teeth. Add the world's smallest ping-pong set, including (3) standardish balls, (2) tiny paddles and a mini-net for our deluxe set! Just try to find them anyplace else for our price!

The manufacturer calls this Toilet Hoops, but we have too much dignity to print that. It’s a 5-1/4” dia suction-cup-mounted basket and backboard, a 27” x 30” felt court for the floor, (3) 2-3/4” dia basketballs, and a holder for the balls that you can mount near the toilet so you can be like Mike. Includes a “Do Not Disturb” sign for the bathroom door.

Replace them with this marble game set: (13) assorted 5/8” dia glass marbles, a 1” dia glass shooter, 16”-square denim game mat marked for (3) games, a storage bag and a sheet with the rules to settle all of those schoolyard disputes.
