The video is about creating perfect ice spheres. The host remembers trying to create perfect ice in the past without success. He then shares a method he discovered online to create perfect ice using a Styrofoam box and a pot with a hole underneath. The ice is frozen from the top down, trapping air at the bottom. After 48 hours in the freezer, the ice is cut into two parts, with the whitish part removed to reveal crystal clear ice. The host tests the method with a Styrofoam box, but it cracks under the pressure of the expanding ice. He concludes that using a container in the shape of a sphere would be easier for future attempts.
1. Last week, an aluminum ball was created using aluminum foil and was well received.
2. The host previously attempted to create perfect ice but had difficulty due to the air trapped inside the ice.
3. The process of creating perfect ice involves freezing water from the outside in, which helps to prevent air from getting trapped inside.
4. To achieve this, an ice cube tray is insulated and then frozen, causing the ice to form from the top down. This pushes the air downwards, resulting in a clear ice core and a whitish outer layer.
5. The whitish part is then cut off to reveal the clear ice.
6. In practice, a Styrofoam box is used instead of an ice cube tray.
7. The Styrofoam box is insulated and filled with water, then frozen for 48 hours.
8. The ice inside the box expands, causing the box to burst.
9. To prevent this, a black bag is placed inside the box to separate the ice from the Styrofoam.
10. A small pot is also placed inside to separate the ice that is to be made crystal clear.
11. A hole is opened under the pot to allow the air to escape, preventing it from being trapped inside.
12. Some form of support is placed at the bottom of the pot to keep it as high as possible, closer to the surface of the water.
13. Once the ice is formed, it is removed from the box using a pot and a small bottle.
14. The ice is then transformed into a ball using sandpaper.
15. One advantage of ice over aluminum is that it melts and automatically smoothes out.
16. However, the process of shaping the ice into a ball is challenging and requires careful handling to prevent the ice from melting.
17. If the process is to be repeated, a container that is already more or less in the shape of a sphere would be easier to deal with.
