The video is about a group of people experimenting with a freeze dryer to preserve various candies. They test out different types of sweets, including gummy worms, Skittles, saltwater taffy, and ice cream sandwiches, to see what works best in the freeze dryer. The results are often surprising, with some candies changing texture and flavor significantly after the freeze-drying process. The group enjoys sampling the freeze-dried treats and notes that some, like Skittles, become crunchy and have a concentrated flavor. They also try out some new candies, like saltwater taffy, which they find to have a unique texture and flavor after freeze-drying. Overall, the video is a fun and lighthearted experiment that showcases the possibilities of freeze-drying different types of sweets.
Here are the key facts extracted from the text:
1. The freeze dryer removes water from substances, but it doesn't work well with chocolate because chocolate doesn't contain much water.
2. The freeze dryer was pre-cooled to a very low temperature to freeze the ice cream sandwiches before the freeze-drying process.
3. The freeze dryer gets as cold as -70 degrees Fahrenheit.
4. The freeze dryer has a vacuum pump that removes the air from the chamber.
5. The trays in the freeze dryer have heating pads that warm up the food from the bottom.
6. The freeze-drying process causes water in the food to go from frozen to vaporized without passing through the liquid state.
7. Gummy worms, gummy cherries, and other gummy candies change texture and size when freeze-dried.
8. Caramel can expand and change texture when freeze-dried.
9. Nougat can become crunchy and snap in half when freeze-dried.
10. Skittles can burst open and change texture when freeze-dried.
11. Saltwater taffy can become similar in texture to meringue when freeze-dried.
12. Freeze-dried saltwater taffy can dissolve in water.
13. The freeze-drying process can take around 11 hours, but the actual time may vary depending on the substance being freeze-dried.
