For a class of 30 students, you need:

• 38 brown paper lunch bags
• 100 sturdy toothpicks (plastic cocktail-type ones work especially well)
• about 80 red jelly beans and 70 pink jelly beans to represent tongue rolling alleles (other types of candy, such as gum drops and/or miniature marshmallows may be substituted, and other color combinations may be used for this and the next three items)
• about 100 purple jelly beans and 50 white jelly beans to represent eyelash length alleles
• about 90 black jelly beans and 60 blue jelly beans to represent eye color alleles
• about 80 orange jelly beans and 70 yellow jelly beans to represent ear lobe attachment alleles
• 15 sheets of construction paper
• transparent tape
• (optional) photocopied pictures of George W. Bush or Michael Jordan, and Tom Cruise or Matt Damon, that clearly demonstrate attached earlobes (Cruise and Damon) and detached earlobes (Bush and Jordan); these can be obtained by conducting a Internet search using the Google image option
