Look what I have found Look what I have found
Look what I have found Not now...is not the right moment..
I have to record a video :) Mmh..
Fine but not now Go do your homework's
Here we are finally Everything ready for a new experiment
Now I'll turn my phone off But...where did I put my phone?
.... Is he gone? Now I'll show you an experiment
This is dry ice, when you see it It looks like normal ice...doesn't it
But it looks totally different when I put it in water
Look at this And I add also some soap
..in the meantime always thinking to the molecules...
hihihihi
ohh there you are my phone
Oh No!! Stop! Stop I said!! Bye!!
Fine now we can start...but what happened?
So you want to do an experiment with dry ice? Are you crazy? You think you are Einstein?
What next a ring cannon?
What? Ring cannon? Where is it? Where is it? Please!! Why did I said that?
At least you know what is dry ice? Dry ice is a solid form of carbon dioxide
Ar room temperature is a gas But when as been cooled down to a low temperature
of -78° C It becomes solid
That's why when you put it into water at room temperature
It changes again to gas...and we see the bubbles.
This is one of the most fun experiments you can do with smoke
Try to hit the cups Oui!
You need a circular opening It allows the air to be faster in the center
then on the sides And this makes a circular movement that starts
the ring. Five meters
What about you? how far can you hit the cups? If you liked the experiment we can see each
other at the next one Do you speak science?
