Ingredients: 

• 1 can frozen juice concentrate (we used apple and grape)
• 1 1/3 cans boiling water
• 4 envelopes unflavored gelatin

1. Thaw juice concentrate and pour into a medium size bowl.
2. Sprinkle all four envelopes of gelatin onto juice.  Let stand while you boil water.
3. Pour boiling water into juice mixture and stir for about 5 minutes, until all gelatin is dissolved.
4. Pour into a 9x13 inch pan and refrigerate for about 3 hours until firm.
5. Cut into cubes.

Children can eat the cubes as they are or joust them.  (Carefully poke them onto skewers or toothpicks.)
