Each of these 20 marbles has a magnet inside. There are countless experiments one can do, from stringing them together to building 3D structures. It is actually harder than it looks since one has to account for a complex 3D interaction of magnetic fields. Great fun! Set contains 20 magnetic marbles packaged in a handy, reusable plastic container, and it comes in assorted colors.

Good idea but weak magnets
Diana from Usa, CA, santa ana
The kids liked them but I jad to supplement some strong magnets to make it fun. Warning: they look like bubble gums so keep them out of small children's reach.
Magnets are amazing. ..

My kiddos loved these and now the next generation will have a chance to play with their magnet wands and marbles, too.

Love the bright colors. Think he will be thrilled.

... but the magnets are pretty weak. We used these for magnetic painting and if the paint was a little think the magnetism wasn't strong enough to move the paperclip we were dragging. Still fun for showing the basics of magnetism though
