This experiment demonstrates how water at different temperatures has different densities, creating beautiful layering effects. You'll see how warm and cold water interact and learn about density ...

You just tested the density of different temperatures of water! The first time, the cold, blue water sank into the red, warm water. We saw purple water through both glasses. This is because the ...

On Tuesday, we're talking about cold and warm air. You can SEE how weather works with this experiment ... of cold water (below 50. You could add ice to chill the water.) One cup of hot water ...

The experiment was inspired by reports of the Mpemba effect, the counterintuitive observation that hot water sometimes freezes faster than cold. But experiments studying this phenomenon have been ...

FROM BOILING TO FREEZING A cup of boiling hot water ... at-home experiment has a sad consequence FOUL: So, apparently, tossing a pot of boiling water into the air when it’s really cold is ...

This experiment deals with density (how heavy something is) and the effects are demonstrated using eggs. You'll also need two glasses, water ... Air has density too. Cold, dry air is more dense ...

This easy science activity demonstrates the difference in density between hot and cold water. It can be a bit messy so you may want to try this outside. We're joined by BASF employee, Casey ...

Warm air is lighter and less dense than cold air ... It's a simple experiment that can be done anywhere with just a balloon and plastic water bottle and some hot water. Stretch a balloon over ...

It sounds like one of the easiest experiments possible: Take two cups of water, one hot, one cold. Place both in a freezer and note which one freezes first. Common sense suggests that the colder water ...

A science video maker in China couldn’t find a good explanation for why hot and cold water sound different ... fourths of the participants in her experiments could in fact detect the difference.

But for a bit of an experiment, I set out to determine which washing temperature is the perfect one for bath towels, hot or ...
