Having recently acquired a propane barbeque, I made a hose to allow the propane tank to feed the gas lines for $39.00

It also came with two digital thermometer forks.

How might they compare to the one I have in my kitchen drawer?

I plunged them together into warm soup: 143, 145, and 139.6 degrees Farenheit.

Then I put them into a known temperature source – me. The red one shows 98.6 – medical accuracy!
