Three plastic cups are stacked inside each other and a temperature probe placed between each cup. Before stacking the final cup hot water (take care) is poured into the middle cup. Quickly stack the final cup and start logging!
What do think will happen?
Will the temperature rise at the same rate in all three cups?
You will find a sample result in the Stack SID file
