Our toddler actually sat still for a whole hour at the airport gate, and the magnets are strong enough that the pieces stay together even when she shakes them. The two shapes are perfect for little hands to figure out on her lap tray.

We take these everywhere now — the magnets are strong enough that the 6 block set stays together even when my toddler shakes it on a bumpy flight. The triangular prisms and parallelograms make fun little towers or animals, and it's nice that they're compact enough to toss in the diaper bag.

The magnetic blocks click together nicely, and the triangular shapes are perfect for little hands to build with on the plane. My toddler stayed entertained for a solid 20 minutes during our flight.
