Vortex Cannon
Aim: To modify our vortex(change the shape and size) to see how far it shoots.
Equipment: Bucket, Rubbish bag, and tape.
Method:We are not making a ordinary homemade vortex using a cardboard. Instead we are using a bucket. First we tape a piece of rubbish bag tightly on top of the bucket(this acts like the side of the cardboard where you squeeze it)
Results: When we tested our vortex, we started off in a 3 metre line. After one of my partner smacked the vortex on the rubbish side the row of cup barely moved. The best vortex in our class made it to 3 metres in two smack.
Discussion:If we do it again, I would change the size into a smaller hole. I think that the smaller hole would make it further because there's a lot of air trying to get out.
Hi Sofia, I liked how you added a picture and how you explained the result and discussion. I can't really think of anything that you could work on. Why do you think your vortex cannon couldn't knock any of the cups?
