Very interesting. Very interesting.

Spring recovery ... I hope he patented the invention!

On another note, many of us have flown those old rubber band launched rockets that would open up and release a parachute once the air friction would lesson near apogee and a flap would release.

there there was a similar design where magnets were used to act as a release mechanism ... let me see if I can find that patent...

The magnet is drawn forward, Faraday's law, and that activates the parachute release.

I am looking for a picture for the commercial packaging, please hold... can't find a pic of the commercial product, only the patent drawings
