Germination Issues

yo,
I recently found a bagseed. I let it chill for a bit and it turned darkish brown so I decided I should try germinating it. I followed a tutorial online somewhere that called for putting the seed in a glass of distilled water with constant temp. After a day the seed sunk to the bottom.
It's been a week and nothing has happened further.
any ideas?
cheers

You left the seed in a cup of water for a week? You might have drowned it. Once it sinks you should pull it out and
A) plant it (in soil)
B) put it in paper towel

personally I prefer the paper towel method.

You're seed might be bunk but you can still give it a try if you want.
