And the world is a better place! Now remember. Don't sit down on your tire while going down hill!!!
So you accidentally bought 10 lbs of sheet metal screws on eBay when you thought you were buying sheep meal stew... What to do? You could make a trap door in your car and spread them all over the road when the cops are chasing you like James Bond. Or you could do something productive and potentially awesome. Make studded bike tyres for your winter commuter!!
Step 1: What You Need
So you've decided to use your screws for good rather than evil. Good for you. There are a few things you'll need:
A tyre (tire for us Americans)
A screw gun machine thingie
The correct bit for your screws
A milk crate
An assistant to hold the tire open
