This is me watching and guessing which marble will go the fastest. I was wrong when I said the straight one because it was the bendy one. It went faster because it got more speed and it was like Newton's first law.
This is me trying to see which things are attracted to the magnet.
This is the vacuum tube. I liked it because when I put the balls in and you shut the door, the air comes in and the balls go so fast through the tubes. It almost bursts through the plastic!!
