The video features a vintage toy from 1977, a dairy cow that can produce "real milk". The host, Mike, unboxes and demonstrates the toy, which comes with a small field, a container, and "milk pills" that are not toxic but not meant to be consumed. The toy is designed to mimic the process of milking a cow, and the host is excited to see if it still works after all these years.
As Mike assembles and operates the toy, he explains the process of milking and the science behind it. He also discusses the different methods of preserving milk, including pasteurization, ultra-high temperature (UHT) treatment, and sterilization. He notes that each method has its advantages and disadvantages, including the retention of nutritional properties.
Throughout the video, Mike expresses his enthusiasm and curiosity about the toy and the process of milking. He also acknowledges the potential controversy surrounding the toy, as it involves children playing with small pills that are not meant to be consumed.
Ultimately, the toy is successful in producing a small amount of "milk", and Mike is delighted by the result. He concludes the video by reflecting on the experience and inviting viewers to join him in the next episode.
Here are the key facts extracted from the text:
1. The toy is a dairy cow from 1977 that can be ordered to give real milk.
2. The cow comes with a container, a little field, instructions, and small white pills.
3. The pills are not toxic but should not be taken.
4. To make the cow produce milk, one of the pills is placed in the cow's udder, and then water is pumped into the cow by moving its tail.
5. The milk is produced by dissolving the pill with water, and it comes out through the udder.
6. The toy also comes with a small book that teaches about the life of cows and the process of milk production.
7. The book explains that milk is an excellent culture medium for microorganisms, which means it can go bad quickly.
8. There are three methods to preserve milk: pasteurization, ultra-high temperature (UHT), and sterilization.
9. Pasteurization involves heating the milk to a high temperature for a short time to kill some microorganisms.
10. UHT involves heating the milk to a very high temperature for a short time to eliminate all microorganisms.
11. Sterilization involves heating the milk to a high temperature for a longer time to eliminate all microorganisms.
12. Each method has its advantages and disadvantages, including the retention of nutritional properties.
13. Pasteurization retains almost all nutritional properties, while UHT retains a large amount of nutritional properties.
14. Sterilization does not retain as many nutrients because the heat destroys them.
15. The loss of vitamin C varies depending on the method, with pasteurization losing 5-10%, UHT losing 10-20%, and sterilization losing 30-60%.
16. The toy is still functional after 40 years, and the host is impressed by its ability to produce milk.
