When Ian and I got to Jonny’s house Jonny told us about his Idea. We were going to hit a water bottle into a cooler. Ian and I agreed. We started building, but we had one problem. How are we going to get an object to the top of the cooler. That’s where I came in. I said we should put dominoes on a box onto a higher box etc. Then when we reached the top the domino would hit the water bottle into the cooler.
