What makes a winning can in a high school soup can race?

[sugarfreeky22]

my class is doing the typical soup cna race this friday, and i am in desperate need of suggestions! we have to come up with the fastest and slowest cans, both stock and modified. Modified can include basically any addition or alteration to the can excepting the addition of motors

fast = reduced friction, solid contact with the race track, perfectly round wheels, lower center of gravity, increased mass (or density like adding lead weights)

slow = increased friction, bad wheel train, lighter weight

There are a few key factors that can contribute to a winning can in a high school soup can race. First, the can should be lightweight to minimize friction and allow for faster movement. This can be achieved by using aluminum or plastic cans instead of heavier materials like steel. Additionally, the can should have a streamlined shape to reduce air resistance. This can be achieved by smoothing out any bumps or dents in the can and adding a pointed front and tapered back.

In terms of modifications, there are several options that can improve the performance of a can. One option is to add wheels or bearings to reduce friction and allow for smoother movement. Another option is to add fins or wings to the sides of the can to improve stability and control during the race. These modifications can be made using materials like cardboard, plastic, or even paper.

It's also important to consider the weight distribution of the can. A can that is too heavy on one side may tip over or veer off course during the race. To prevent this, you can add weights or adjust the positioning of the weights inside the can to achieve better balance.

Lastly, for the slowest can, you may want to consider adding extra weight or creating a more bulky shape to increase friction and slow down the can's movement. For the fastest modified can, you could consider adding a small fan or propeller to the back of the can to create a propulsion effect.

Remember to test out different modifications and designs before the race to see what works best for your specific can. Good luck with your race!
