New Homeland Security bill is a downer for model rocket fans

Stefan sez:

A last-minute amendment to the Homeland Security bill is going to make it tough to buy and transport the larger model rocket motors.

The new restrictions are intended to keep Ammonium Percholorate, a powerful oxidizer, out of the hands of terrorists. But the AP in "composite" rocket motors is bound up in a rubbery mixture that's a pain to ignite, much less make go boom."
