Audie,
I can really relate to the "boy that refuses to grow" up in us. The grandkids bring out all the best of our mischevious nature and drives our kids crazy. My children want to know what happened to the disciplinarian they grew up with. Wonder what they will think when I try the stuff you posted above. We have a big 4th of July party every year, the marshmallow and tube trick should provide much entertainment and make my young ones think I'm the greatest. I'll bet my son in law will be clueless when I fire up his air compressor. Thanks Old Boy for teaching another Old Boy a new trick.
