You never know when this will be useful: this video shows you how to make fire using a potato, toothpaste, salt, cotton, and toothpicks. [warning: gratuitous use of a girl in bikini in start of video]

I don't think so.
All these new how-tos that are coming out lately are like hiccup cures: intended solely for the entertainment of those watching.
That was pretty cool. You can also turn on a small lightbulb with a potato or a lemon.
- asked a neighbor for a lighter
- used his stovetop
- rubbed two sticks together (or used steel wool)
- etc.
I was just waiting for him to pull out a lighter and light the whole contraption on fire. Interesting little battery, but rather ridiculous concept to use if trying to "impress" a girl.
I should try it sometime-- it's not practical, but it's immensely awesome.
The how-to should have been how to get a real bikini girl to pose for your movie rather than filming a magazine pic.
Useless .. Sorry ..
