Demonstrate Disecto by cutting carrots placed both in the top hole and the wrist hole of Disecto. Yes, the carrots are sliced! The volunteer now puts his hand through the wrist hole, and he is secured in. Place more carrots in the top hole and through the bottom hole. Your volunteer is nervous now! Push Disecto's steel blade through the carrot in the top hole, slicing it in half! Continue pushing the blade right through the volunteer's wrist, and chop the carrot in the bottom hole! Of course, the carrots are sliced, but the volunteer is unharmed.
