And that's the technical term, "the bendy thing." I should call it a technique and claim to have invented it, maybe I could give it my name. "Kara's bendy thing wire technique method." Yeah, that's it.
Anyway, here's what I do:
Start with your average styrofoam ball and a wire (This also works with styrofoam cones if you're so inclined.)
Bend the part that's sticking out the top all the way down to anchor it.
That isn't going anywhere.
Now turn it over, and at the base where you inserted the wire, bend it at a 90 degree angle.
Now bend it back onto itself so that it makes a decent-sized loop to keep the bottom in place.
Bend the wire so that it's once again straight up and down the way that you inserted it into the ball in the first place. The little loop will be anchoring the wire against the base.
Press the loop into the styrofoam.
Now that end isn't going anywhere either.
