There are several good DIYs you can find on the internet. This isn’t one of them!
There’s photos going viral that claim: “If you form tinfoil into a sphere and microwave it for 6 to 7 minutes it will smooth out and be shiny” Really?!
Worst. Handcraft tip. Ever.
That’s what my colleague said. Here’s why: If you put tinfoil into a microwave, bad things happen. Not at first, though. A cavity magnetron inside the microwave oven produces small electromagnetic waves with 0,3 to 300GHz. These waves jump around inside the microwave oven until they get absorbed by the food you usually put in there, which is why they get warm. But tinfoil contains many electrons which cannot absorb the microwaves, but reflect them further. This causes sparks and fire inside the microwave oven!
Where did the claim originate?
Somebody from Japan apparently was very bored. So he created a ball from 16m tinfoil and worked on it for 2 hours with a hammer, until he got a shiny ball.
It started with a joke:
wrap your food in foil paper and put it in the microwave for 1 min it heats up faster

“wrap your food in foil paper and put it in the microwave for 1 min it heats up faster”
Then it started to take off: A user claimed to have put the ball inside a microwave:

And in the end somebody used the original pictures and combined them with the false claims and sold them as “life hack” or “DIY tip”. Why? Because they were trying to prank unsuspecting users.
But I want a ball like that!
Then build one! Please without the use of a microwave oven. Buzzfeed Japan has a description of how to do it the right way. Oh, and in case you can’t read japanese, we’ve got you covered:
1. Make a ball out of tinfoil with your hands.
2. Use a rubber hammer to round it out some more.
3. Work on that for approximately 2 hours. Alternate between hammer and your hands.
4. Polish the ball with abrasive paper, preferably the smoothest one you can find.
5. Use some liquid abrasive to polish the ball with some cloth to get maximum shinyness.
