2/3 cup of juice
mixing bowl and spoon
square cake pan
Casting the Spell
Ask the Professor to boil the juice.
Pour one packet of unflavored gelatin into a cake pan. Ask Professor to add the boiling juice. Stir until the gelatin is dissolved.
Sink straws into the mixture so they will fill up with the gelatin. Place jars on top of the straws if the straws float. Refrigerate until firm (approximately 4 hours).
Place the chilled straws on a cutting board, and using a rolling pin, gently push and squish the worms out of the straws.
The Science Behind the Spell:
The worms are colloids too. A colloid is when you evenly distribute bits of one substance through another.
Other examples of colloids are:
Gels -- liquid floating in a solid. Gelatin floats
Aerosols -- liquid floating in a gas. Fog floats water droplets in air.
Foams -- gas floating in a liquid. Whipped cream floats gas in cream.
