We got DS6 some magna-tiles for Christmas. I feel a bit stupid, but I can't seem to use them as pictured. Is there a trick to them? They don't stay at a right angle to each other unless you build a full 3-d shape with all sides, just sort of fold in on each other.
I've popped them away for today until I can work it out because ds isn't the most patient of children. I can see these being really frustrating when they won't build!
