When we went to the science museum it was because there was a chemistry workshop, called the Super Cool Show.

I'm going to tell you what we did there. The man Carlos, showed us a gas, called Liquid Nitrogen, which if you ever put your hands near you will get frost bite, because it is -100 degrees Celsius. He also showed us something we didn't believe he could do. He got a banana, put it in the liquid nitrogen, and waited for a couple of minutes. Then he got a block of wood, put a nail in it, not fully, and then asked Fatima to hit the nail into the block of wood... with the banana! And it worked! Carlos also showed us how liquid nitrogen could shrink and grow back metal. He had a metal stick with a ball on top, and another with a hole in it, at first the one with the ball on it could fit through the one with the hole, but after he put in the liquid nitrogen, the stick with the back couldn't fit through, then he put the one with the hole back in the liquid nitrogen, and took it out and the one with the ball could fit through it!

And that's our trip to the science museum about the chemistry workshop.
