Sharko posts...

Usually I do a lot of experiments with our son (nickname Sharko) and as he is growing, we have been expanding our discussions about the experiments and topics.  We thought it might be fun for him to write the blog with a little editorial help from me so kids can relate to them better.  So, we will be posting experiments, snippets of amazing science stuff we sniff around etc...To explain how any particular experiments work or theories behind, I will try to fill in or explain to Sharko who will in turn write it in his own words.....Kid's blog for kids...

We will post videos/pictures of the experiments we do at home as well as cool videos etc from other sources too.  Especially videos like this one that we cannot do where we are and time of the year...

As his first blog experiment, he chose to rewatch the video of what happens to hot water in really cold weather...And now I turn the blog to Sharko...

Today we are going to see what happens when hot water is thrown in cold weather.  For this experiment, cold weather means below Freezing temperature.  For example, -30C is very cold and awesome to do this experiment.  Since we dont live in a cold place, we found a video to show.

Watch this experiment -

When you throw hot water in such cold weather, it freezes before it touches the ground. you see a cloud of snow and not water falling to the ground.

The scientific name for this behaviour is very funny.  Its called Mpemba effect.  warm or hot water freezes much faster than normal water!!.  Isn't it cool?
