Invention: Tribeater
Hello, my name is Aletha. My invention is called the Tribeater.
I noticed a problem one day when I was mixing a batter that was too thick for only two beaters. The beaters were not strong enough to mix the batter and the beaters stopped. I was frustrated and did not want to continue. The Tribeater is a perfect solution to my problem. It would provide more power.My device consists of a fly wheel which connects with gears. When I turn the handle, the fly wheel turns the gears and the gears cause the beaters to turn. When the beaters turned, they mixed the batter more easily than two batter equipment now available on the market. The Tribeater consists of a fly wheel which connects with gears. When the handle of the beater is turned, it will cause the gears to turn, the gears would cause the three beaters to turn.
In order to determine that my invention was needed, I watched commercials on television and interview friends, neighbors, family and teachers weather they had seen a Tribeater before.

Hello, my name is Marvina. My invention is called Sleeves So-Dry. Have you ever had to wash dishes just before you removed or put on your nice clothing, and you didn't want to roll-up your sleeves? With my invention, you no longer have to worry about wet sleeves..
Parts of the Invention
1. Elastic strips for the tops and bottoms 2. Plastic Bags (B)
Construction
My invention is constructed of two 11" x 17" plastic bags and 2" wide elastic trim. The plastic bags were cut to fit the arms. Then I cut two strips of elastic and sewed them to the tops and bottoms of both plastic sleeves. When you slide your arms through the sleeves, the elastic provides a tight fit around my upper arms and wrists.
