Place egg whites in a mixing bowl and set aside.
Combine sugar, corn syrup and water in a sauce pan and bring to a boil.
Stir occasionally until the sugar dissolves and allow the mixture to heat to 250 degrees (using a candy thermometer).
While the mixture is boiling, beat the egg whites until stiff peaks form.
Beat in the cherry Jell-O and vanilla extract. Allow to sit.
When syrup is ready, start mixing the the Jell-O mixture again on high and gradually add the syrup to the mixing bowl while mixing.
Allow the beater to work for 5-7 minutes or until the mixture begins to thicken and lose its gloss.
Drop by teaspoons (make sure your spoons are greased) into a silicone mold or onto a pan covered with waxed paper.
Allow to set overnight or until firm.
