Safely putting spikes on my helmet
Hello! I've been using my bike as my primary form of transportation for a while now, and decided that I should probably finally get a helmet. I simply refuse to leave something I'm going to be using long term unmodified, and I'd really love to be able to add spikes to my helmet. I know that this could potentially compromise the safety of the helmet, so I'm trying to figure out a way to get do it safely.
​
I was thinking I'd make spikes out of a soda can so that they're not solid pieces of metal, and attaching them with something like hot glue or some other weaker adhesive so that they'd snap off easily in case of an accident.
​
Is this something that can be done safely, or is it a fools errand? I'll settle for just painting the helmet or putting stickers on it if I have to, but I'd really love to be able to fulfill my spiky visions.
