Yes, I have a couple really good burn scars. TB can claim the "bloop" badges, I'll just take my scars.
So, we've morphed into OTJ injuries-
"BackInTheDay"..... refrigeration units didn't have all the mesh guards to keep all the body parts out of the high velocity rotating blades. Explanation--- at 15 years old...I reached into the cooler for a gallon jar of diced spuds in water and my right hand middle finger went through the wires and came in contact with the spinning blades of the cooler fan.....
I was self employed for a time, running a little cafe, and became Home Sick with a Cold (prolly back in the early 90's). Remedy of the Day was Thera-Flu.
I nuked a cup of plain water for about 2 minutes, removed the cup from the micro, perched it between my knees and dumped the Thera-Flu packet into the micro'd water...and......DON'T DO THIS!!!!!!!!!
BoilingLavaWater, 3-rd degree burns on the insides of my knees. Something about static water pressure, and heated water,a nd you can actually fill a glass fuller than the rim...and talk to someone else about the phisics..... Suffice it to say
I had no insurance....so when the blisters were really big and nasty, I went to my Mom and had her use her embroidery scissors to cut off the blisters from the insides of my knees. Still have the scars.
Of all the physical accident crap that I've done or subjected my parents to,.....(this includes some "crafty" accidents like 3rd degree hand burns from a soldering iron, and lacing open a finger with a razor blade...) I think my mom disliked treating the knee-blisters from the Exploding Thera-Flu the worst.
and then there's Silvadine!!!!!!
