Hope you enjoy trying this.
Weather fronts

What you will need:

a.. A large, clear tank
b.. Warm and cold water
c.. Two plastic cups
d.. Small stones
Fill the tank with normal water and leave this for a few hours to come to
room temperature.

Place a few small pebbles in each of the two cups to act as weights. In one
of the cups place some hot water and a few drops of red food colouring. Fill
the other cup with very cold water and add some blue food colouring. Place
the two cups into the water at the same time, one at either end of the
tank - the pebbles should hold the cups at the bottom. Carefully watch how
the two different coloured waters move. You should see that the warmer red
water should raise to the top, and the cooler blue water should sink to the
bottom.

Much of our weather is caused by the interactions of different air masses.
Warm air (shown by your warm red water) is less dense than cold air (cold
blue water), so warm air rises and warm air exerts less pressure than cold
air. As air cools, it becomes denser, so it sinks and also exerts greater
pressure.

Another experiment:

Take 3 coffee cups. Fill cup #1 up with hot water. Fill cup #2 with
icecold water. Fill cup #3 with room-temperature water.

Now, stick your lefthand pointing finger into cup #1 and your righthand
pointing finger into cup #2 simultaniously and keep them there for 30
seconds.

After the 30 seconds, stick your lefthand pointing finger AND your
righthand pointing finger simultaniously into cup #3.

Your lefthand pointing finger will now tell you the water in cup #3 is
icecold whilst your righhand pointing finger will tell you the water in
cup #3 is steaming hot.

I guess that definately means a MENSA account for me.

Well, I doubt if being able to copy/paste and not attribute the source
qualifies one for MENSA. Maybe DENSA....

Only if he can do the experiment within a certain timelimit. Mensa tests
are, after all, speed tests rather than intelligence tests.

The site you posted didn't mention the source so what's the difference.

Because possibly it *is* the source?
