Materials List: Proof of Concept:
Miracle Drug Encapsulation

Each group needs:

  • 1 perforated, hollow plastic ball, such as a 4-inch diameter Wiffle® ball; such as a pack of 6 for $5.49 at Target (see Figure 1); save any plastic netting that comes with the packaging
  • colorful drink flavoring powder, such as a Kool-Aid® packet for 20¢ at grocery stores or as available in multi-serving containers
  • There Will Be Drugs Worksheet, one per student
  • (optional) computers/tablets with Microsoft® PowerPoint® or other drawing application, for students to draw design diagrams; alternative: have students draw by hand using paper and pencil
    Two photographs in a school lab shows an assortment of supplies collected for the activity; items include three packets of white, perforated, hollow plastic Wiffle® balls in plastic netting (six balls per packet), containers of Kool-Air® mix, two packets of balloons, three bottles of glue, plastic paint tray liners, stacks of cardboard pieces and white paper, dish foam roll, roll of weed barrier fabric, rolls of tape, four rolls paper towels.
