In the comments section of that article, some one mentioned that electric tape and a lid would provide a water tight seal and this idea hit me.
With all the terrariums and plant growing bulbs on here, let's do something different.
Step 1: Materials
-Light Bulb (The bulb I used was the frosted looking 60 Watt one from GE.)
-Coke Lid (In my case, I had to use one from a 2-Liter bottle. The 20oz ones were too wide to fit)
-Candle or other flame
- (optional) Round File
- (optional) Coat Hanger
