Flying Glider Colour-in Kits (Pack of 8) Pocket Money Toys, Assorted Designs, Easy To Assemble, 18cm Long

What you're getting

You get eight flying gliders here, each one 18cm long and ready to build. They're paper-covered polystyrene, so they're light enough to actually fly once you've put them together — which takes about five minutes, no fiddly bits.

The clever bit is that they come blank, so your kids can colour them in however they fancy. Fibre pens or paints both work fine. You'll end up with eight completely different gliders, which means less arguing about whose is whose.

Assemble, decorate, then chuck them and watch them glide. Dead simple, and it keeps them occupied for a good while.
