In this video I build a simple, DIY glove box out of easily-sourced parts from the local hardware store. This project is based on a video by Make Magazine:    • DIY Hacks & How To's: DIY Glove Box  

Cost: ~$40
Time: ~1 hour

The argon cylinder I bought from my local AirGas branch - they have a 'showroom' you can just walk in and walk out with a tank of gas!
