Chris,
I looked it up on Google.
A case of 20 targets for $98.00 is too much for me.
I can barely afford Rohrbaughs.
When I was a child, I used to buy a chemical at the hardware store, which you drop into water, and it would release a gas.
It was the same stuff they used to use in auto lanterns.
Now that was fun. You can do a lot for 25 cents worth.
For some reason, I can't remember the name right now.
