Very impressive transformation! Fun and instructive shape memory effect!

I bought 3. One for a clown frined, one for me, and one for some science kids. The video shows a tangled wire that bounces back into "hot". Very cool... not. In reality, the two ends gets caught in the O and you have to spend time untangling it. I tried just barely scrunching the wire and just pulling it out straight. Out of 8 tried on all 3 only once did one of them go back to HOT without help. The video is not a real example of how it works. want a refund.
