If anyone is interested, here is an experiment I did with my DS Cub Scouts a couple of years ago.
Drop a watermelon on concrete. It breaks.
Put another watermelon in a helmet. (I looked for a smaller one that would fit in a helmet.) Drop it all with the helmet hitting the driveway. Watermelon does not break.
I must admit I was nervous because I didn't test it since I didn't want to throw away two helmets! It worked, and we took the watermelon inside and sliced it for a snack. The plastic part of the helmet did crack.
That is a very interesting experiment. When we start back up after school starts back, I will have to demonstrate this with my scouts!
Yes, always! My son is the poster child for helmet use. When he was 4, he was riding his bike and decided to run into the porch (about 3 inches high) to see how fast he could stop and went over the handle bars. His head bounced off the porch and and then bounced off the cement driveway. It split his helmet in half. We walked away with 4 broken teeth on the top. That was it. If he had not had the helmet on, he would have had a major head injury.
I was a paramedic for 10+ yrs and always required helmet use of my kids because I have seen the results. Before my son's accident, my parents had always said its too hot, why don't you let them take the helmets off, after the accident (which my mom and I witnessed) it has always been put your helmets on. We don't get an argument out of either kid.
I'm willing to bet that most of you who say your kids wear helmets EVERY SINGLE TIME NO MATTER WHAT have young kids, otherwise you really don't know. I see many kids riding around town with their helmets hanging on the handle bars. Some of their parents probably believe that their kids ALWAYS wear their helmets. It gets much more difficult as your kids get older.
Not true here. My son will be 13 in Nov, my dau is 6. If it has wheels, they put on a helmet. Whether it is their scooter, bicycle, dirt bike, or 4 wheeler. This rule also applies for any friends that come over. Even if their parents don't require them to wear helmets when they ride at home, when they ride at my house, they wear helmets. We have extras from toddler size to adult.
