Hi welcome back😃
In room 9 for topic we needed to make a marble run. We only had paper and tape. We had 5 pieces of paper 5 bits of tape. Some people did it with their friends, I didn't. We had to make the marble run go slow. I didn't make it steep because then it will go fast. When we were done we tested them out to see if it went slow. I chose this design because I thought It will go slow.
