Shield & Helmet ???

Hubby found some videos on you tube the other day of some really outrageous K'Nex creations.  Of course The Professor was intrigued.  He proceeded to disappear into his work area closet and has barely been heard from since. :)  He created a shield and a helmet.  I guess he thinks he's going into battle or something ;)

He even created a nose guard, chin guard and a sun shade :)
