Putting a brick in a toilet reduces the amount of water in each flush because the brick takes up volume; thus, saving water and money in our homes. You can also use any other object that takes up volume in the tank (i.e. a filled up water bottle).
The average size brick is 8" x 4" x 2.5", therefore creating a volume of 82 cubic inches. The average toilet uses 4 gallons per flush. Therefore, placing a brick in your toilet basin will save, on average 0.35 gallons per flush. The average toilet is flushed 4 times per day making the average daily savings 1.40 gallons per day.
You can use any number of types or sizes of bricks, which will change your results, but make sure that the brick fits securely at the bottom of the basin as to not cause the brick to knock against any internal parts of your toilet. Make sure not to get a brick that is degrading too much or too old as the particulate will circulate in your toilet bowl and potentially leave stains.
Additional Costs
You can get a brick at your local hardware store for free, usually or your local scrapyard. If you want to buy one, http://www.best-price.com/procSystem,showProduc... should work.

There's also a less wild version of this solution: If your toilet was installed before 1992, add a toilet dam to reduce the amount of water flowing out of it by 35 percent and still leave it functioning properly. Toilet Dams make your tank smaller by using plastic barriers that prevent water from running out when you flush. Standard dam can hold back one gallon of water, some up to 2-3 gallons. Estimating about 10 flushes a day, that is a savings of up to 12,000 gallons a year!!!
You can find toilet dams at your local hardware store or online.
Also, it may not be the best thing to use a brick because it can deteriorate and clog your pipes.
