I have been using the regular ol' 2" 3M #371 packing tape in my trials
this past week. I have to double it up to prevent "blow-ins" but I still
get a pretty good seal...sometimes too well. My current problem is the
ping-pong balls I'm using...they're crap....dollar store...kinda smooshy.
I managed a pretty decent dent in a can today but nothing close to
splitting it open like Dick Peterson's does.
Any other input would be greatly appreciated.
