Bicycle helmet nose protector

If you hit the ground face-first on your bike, you are likely to break your nose and your teeth. Most helmets are of no help in this respect, although the airbag looks pretty good:

My Sportek helmet has a little visor, loosely attached by Velcro, which would provide a bit of protection:

Here I added a zip tie to hold it in place. When I whacked my nose I heard a noise which was probably the visor detaching from the Velcro. The zip tie holds the visor firmly in place and provides a facial crumple zone. Of course this will probably kill you in a accident, so don't do this.
