OK, so after a couple of binnies on the beach, I bought a pack of those heliopter thingmes that have a blue light and you flick in the air.
I have worked out how the make the light come on (winding one wire around another), but how do you make them hover and slowly drift back to the ground? I have sort of worked out how the use the rubber bands like a slingshot, but do I splay the pl;astioc wands, or what do I do?
