Getting Started with Electronics
Wow, it looks powerful, Powerfully cool! 100 watts is the power consumed by the LED, but how many lumens does it putout? If you had the power drawn, we could better decide what type of runtime we could get for a particular battery configuration. Lastly, could you provide any more information for the sourcing of the lense?
Tools and Materials for Arduino
Your First Experiments
I made mine with a Tricolored LED.
I agree with the suggested add-ins, but I have a suggestion for your "Battery Tin." (Step 11) The cardboard will prevent shorts as long as it doesn't move. As you use the things out of the tin the remaining items will shift around as the pack gets moved around. I would suggest adding a piece of electrical tape to cover both ends of each of the batteries. Better yet, use rechargeable battery and a solar cell to recharge them. there are a bunch of Instructable Projects that could fill the bill, but I'll suggest a simple one to start with; https://www.instructables.com/id/Travel-AA-Solar-Ch...
Welcome to Arduino
I don't think it would work, the weave used in socks is generally loose enough to "Breath". And I don't think socks would be too conferrable. After treatment the material gets quite stiff.

Dang, I put out the ca$h for a Dremel brand drill press last month. I might make this just to have the fun of making
If you dilute 50% alcohol with 50% more of water the solution will not ignite even if sprayed directly into an open flame. On the other hand I would caution about spraying any liquid into a "powered" motor though. Too much liquid may cause an electrical short. So with some common sense and a fine misting you'll be fine.
