Pour the water, cherry jello, and milk into a saucepan. Heat the mixture until it begins to boil.
Add the unflavored gelatin powder. Stirring while slowly pouring to prevent any lumps from forming.
Cool the mixture in the fridge for about 30 minutes
Fill the jar with straws while the mixture is cooling.
Once the mixture is cool, begin pouring it into the straws. Again, don't stress about trying to get the jello directly into the straws. They will fill from the bottom up as well.
Place the jar in the fridge for 24 hours.
Run hot water over the bottom of the jar to loosen the mixture. You may need to run a knife around the side. Pull apart the straws and run them under hot water. Squeeze the end of the straw to gently push the worm out from the top to the bottom.
Place them in a bowl for your ghosts...I mean guests to enjoy!
