Supplies and Setup
Supplies
- Grape(s) – we prefer red grapes
- Marking pen
- Toothpick
Set up
- Using a marking pen, mark 4 lines on the grape skin, splitting it into 4, like a beach ball
- Pass the toothpick through the grape lengthwise, as close to the middle as possible
Objectives
Primary objectives
- Dissect two pieces of skin off of the grape, leaving it in an alternating pattern of skin/flesh. To the best of your ability:
- Keep skin pieces removed intact with no buttonholes
- Leave no grape pulp on the skin pieces you remove
- Avoid deep cuts into the flesh of the grapes
Technical objectives
- Handle tissue carefully and gauge tension visually as you dissect
