Scientists Brian Sidwell and Mike Lowe design bicycle helmets by experimenting with shape, materials, and durability. If a helmet doesn’t fit correctly, you might not want to wear it, or it might not protect you well enough. You want your helmet to last for as long as your head fits in it, so how it stands up to the elements is an important factor in its design. Watch this video where the two scientists show how they design bicycle helmets, test them, and show how helmets protect the brain in a crash.
