Empty Bleach Bottles

[Cannonball]

Does anybody have any cool ideas on how to use a growing supply of empty bleach bottles?

And what's up with this odd volume size? The large Clorox bottles are 1.42 Ga/5.38L. Strange.

nope. Sorry. Ran out of ideas when I was 12 and tried to make an instantly refillable scuba tank out of one by removing the bottom and putting a snorkle hose off the top. Oh--and I couldn't get it to work. Boy! that was nearly 40 years ago!

Confusion so you cannot guess the REAL price you are paying. Odd sizes are an old trick. First the bag of coffee is 1 lb for $4.00. Then the bag is the same size, but only has 12 oz, but now costs $3.95. Then it's 11.3 ounces, etc.

To compare bleach prices, convert all amounts to a common unit, like ounces (or litres, if you are of that persuasion). Then multiply by the concentration. This will give you how much sodium hypochlorite is in the bottle. Divide the cost by this amount, to give you cost per unit of sodium hypochlorite.

Example:

Say, you are comparing:

3 quarts of 5.25% bleach at $1.33 (found at local Target)
5.43L of 6% bleach at $2.59 (found at local grocery store)
2.5 gallons of 10% bleach at $3.60 (found at a pool store)

(FYI these are prices I found yesterday)

3 quarts = 96 oz. 96 oz. X .0525 = 5.04 oz. 1.33 / 5.04 = .26 cents/oz
5.43L = 181 oz. 181 X .06 = 10.86 oz. 2.59 / 10.86 = .24 cents/oz
2.5 gal = 320 oz. 320 x .10 = 32 oz. 3.60 / 32 = .11 cents/oz

So, the 2.5 gal of 10% is the best deal by far.

Is recycling cool? Not all recycling centers accept #2 (HDPE) plastic, and my town doesn't, but many do. I'm accumulating it for my next trip to the nearby city where it will be accepted.
