  • 1 HDPE (Nalgene) Bottle 500 ml size
  • 1 Flexible reflector auto shade (the shinier, the better)
  • 1 Large plastic bottle with a screwable mid-section (This is hard to find. I got mine at a dollar store and it contained a lot of small bungees. This is convenient, but not necessary. You can use a 1 liter soda bottle, a half gallon square water bottle or a large jerky container.)
  • Metal duct tape
  • Regular Ducting Tape
  • Self-stick Velcro strips
