Science Roadshow

The whole class had to pay $2 to attend the Science Roadshow, some of us didn't get to pay so our homeroom teachers' covered up for them for free! For 50 Science Inventions that we get to experience and try out! We spent the whole period 1 & 2 on the Learning Street in the Science Room with 7TZ.  The other year 7 classes went There we were introduced to Shane the MASSIVE GUY & Samantha. Shane showed us fire in ice and did an experiment about it.  The experiment was the ball the couldn't fit in the hole, he asked for a volunteer in the audience, Shontelle, in my class, was picked because she was the first one who raised hands. Shane told Shontelle to put the ball (It was an 8 numbered ball from billiards) on the hole (those wands) it did, but when the hole with the handle was put in a small bucket filled with liquid nitrogen. Shontelle and Shane used safety glasses and gloves for safety of course, Shane took out the hole with the handle and it was smoking and freezing cold! Well like a cold smoke coming from your freezer, then Shane told Shontelle to put the ball on top of the hole to see if the ball still goes through but surprisingly the ball got stuck in the hole, it didn't go through, Shane asked Shontelle to do it again and it did the same thing. You knew you lick a popsicle and it so cold that your tongue sticks to it? Well, I feel like that's what exactly happened.

The next experiment we did was burning a galvanized sheet metal (A galvanize is coated with zinc, when a metal gets rusty because of the weather and temperature it makes a metal rusty and to recycle it, they coat it with zinc so it can be used).  The fire changed colours from yellow-ish orange to lime-ish colour, it made galvanized sheet metal melt and turned into glass and turned a hole in the middle.

After all the experiments, we explored and tried all the inventions, they were all pretty cool, there were so much questions in my head in each and one of them, I wish I can tell them to you all but all of you might get bored so I'm just going to make this blog post shorter.
