Heads up on the interesting find I made at my local grocery store.

It's a "Scotch" product called "Instant Power" drain opener. I paid $4.99 for a 1 liter bottle.

Had a friend look up the MSDS on it and here is what we have:

38-50% Sodium Hydroxide
0-3% Potassium Hydroxide
47-62% Water

Good find? If so what is a good ratio (to 1 liter water, etc.) to start with for a simple 12v wet cell experiment?

Thanks in advance!
