Physics? Biology?  
Why does cold tomato juice feel colder than cold soda? Is it because it's thicker and the "cold content" of a given volume of liquid is greater?

Are you tasting one directly after the other? Is there a significant time lapse between the two? Are you taking a drink of something warmer in between the two? (Have you put a thermometer in each to determine whether they actually *are* the same temperature or not?)

Fun science experiments to do in your own kitchen! Now you just need something to blow them up! (isn't that how all great science experiements end?)

the scientific fun kitchen !
blowing up:
egg in microwave
beans, potatoes, corn in microwave.

And pressure cooker. ( starting to boil over the moment one releases pressure )

red cabbage changing color with acidity ( vinegar/juice/wine/bicarbonate of soda )

and then there is fermentation : combining Physics, Chemistry and Biology

I know of cases where after inadvertent experiments the kitchen had to be repainted. ( set froze concentrated orange juice in tight, closed container on upper level of cupboard: forget for a few days: boom: repaint ceiling )

Note to self : need science icon
