*Running the other ice bucket "naked". The cooling surface got down to 0C (even though the display read 7C) | *Running the other ice bucket "naked". The cooling surface got down to 0C (even though the display read 7C) | ||
*Trying something: I put some water from the real ice bucket in the fridge into a tube. The probe said that the fridge water is at 3C. Put the lid on the beads bucket and going to see if the water heats up in about 10mins (if it stays 3C then stuff from the fridge can go in w/o risk of overheating) | *Trying something: I put some water from the real ice bucket in the fridge into a tube.

**So I guess the 0th law of thermodynamics is still true. Beads 7C, water 7C | |||
*With the 2nd bucket, I have allowed it to cool to a reading of 4C naked. I placed the aluminum pan into the 4C Fridge (reading of 6-7C when removed) and placed that into the 2nd bucket. I will see how cold it gets with just pan (closed lid) | |||
**The display reads 4C and the temperature of the pan (the probe is inside touching the pan with the lid closed) is reading 4C. | |||
*Next thing to try: beads plus water. Filling the empty pan with about the same amount of beads as the first with ~250ml of h20 (tap, since DI water will eat the Al pan) | |||
