Really red!  We used apples, brownie bits, bananas, marshmallows, and angel food cake to dip. Great for Halloween, might work for Christmas or Valentines Day.
Ingredients:

• 6 cups light corn syrup
• 4 cups sugar
• 1 cup water
• 1 cup cinnamon candies (Red Hots)

Directions:

1. Bring corn syrup, sugar, and water to a boil.
2. Add the candies.
3. Boil until the mixture reaches 220°F on a candy thermometer.
4. Allow to cool slightly before running through the fountain.
5. Run on high heat.
6. Thin with water if necessary.

Yield: Enough to run through the largest home fountains. Use 1/3 to 1/2 for smaller home fountains.  Multiply quantities by 4 for large commercial fountains.
