Lyle Phifer, Russ' father, taught me a technique for opening containers of
peroxide formers. 

- Gently place the container in a vise. 

- Tighten the vise on the container so that it that can resist the twist
described below. 

	- Placing a round container in a vise with flat jaws may require
	  engineering, but you'll figure it out. 

- Wrap a string at least a dozen times around the cap in a counterclockwise

	- Kite string might be appropriate

- Extend the string to the other side of the room, or even around a doorway

- Pull on the string steadily, but firmly

- The cap will unscrew with no one near to be hurt if an explosion results. 

I have not needed this technique, but I continue to think it would work
quite well. 

Stay healthy,
