Machina Dynamica mini isolators


They look like bedsprings to me. Is this for real? I see many positive feedbacks for the seller.

Those 'bedsprings' are really NASA inertia control parts. The Government paid about $500 for EACH of them, and Machina Dynamica snatched up the surplus for five buck bidding on a cargo container full of them.
So snatch them up while you can.

because a fool and his money.. You may not have any money if you buy these gizmos.. But at least you will have a piece of NASA history. that is the story I heard..

And if you believe this then I have stock in bridge to sell you...
Yeah, they have been cryoed. It makes all the difference between an 9 cent and 9 dollar spring.
