The video features a person attempting to create the world's heaviest standard-sized, fully functional 3x3 Rubik's Cube. They start by comparing their initial attempt, which weighs 953 grams, to a normal Rubik's Cube, which weighs 26 grams. However, they discover that someone has already created a heavier cube using stainless steel, weighing over 1400 grams.
To beat this record, the person decides to use tungsten, a dense metal, to add weight to their cube. They modify the cube's pieces to fit as many tungsten cubes as possible, eventually adding over 1200 small tungsten cubes to the cube. They also create a custom tungsten core and add tungsten putty to fill any empty spaces.
After assembly, the cube weighs 1574 grams, beating the previous record. The person demonstrates the cube's functionality by solving it, despite its extreme weight and tiring nature to hold. To put the weight into perspective, they compare it to 24 standard 3x3 Rubik's Cubes, which still don't match the weight of the modified cube.
Here are the key facts extracted from the text:
1. The world's heaviest Rubik's Cube weighs 953 grams.
2. The creator of the cube made it using a solid stainless steel Rubik's Cube.
3. A standard Rubik's Cube is made of plastic, which has a density of about 1 gram per cubic centimeter.
4. The density of osmium is over 22 grams per cubic centimeter.
5. A solid osmium Rubik's Cube would weigh around 4,000 grams.
6. The raw material for a solid osmium Rubik's Cube would cost over $100,000.
7. The creator of the cube used tungsten to make it heavier, with a density of over 19 grams per cubic centimeter.
8. A solid tungsten Rubik's Cube would weigh over 3,500 grams.
9. The creator of the cube was able to fit 8 big tungsten cubes inside each edge and corner of the cube.
10. The creator also added small tungsten cubes to the centerpieces of the cube.
11. The modified edge piece of the cube weighs 64 grams.
12. The modified cube has a total weight of 1574 grams.
13. The modified cube is heavier than 24 standard 3x3 Rubik's Cubes.
14. The creator of the cube had to sand down the plastic bumps inside the pieces to fit the tungsten cubes.
15. The creator also custom-made a tungsten core to replace the original core of the cube.
16. The center caps of the cube were glued on to prevent them from falling off due to the added weights.
17. The cube's dimensions are within the standard size of 57 millimeters from center to center.
