It seems that the contents of the jar are something completely colorless.

That's true. If the invisible coating itself is still colorful, how can people believe that it can make objects invisible?

Fortunately, the special brush did not become invisible after being dipped in the invisible paint; it remained the same as the previous brush, except that the yellow brush head became translucent.

Sure enough, as the brush head touched the apple and brushed it down little by little, the apple slowly disappeared from under my eyes and finally became transparent.

Of course, in Li Lechen's view, the outline of the apple was still there, only it had turned into a translucent golden yellow.

Has it really become transparent?

Is it invisible now?

Li Lechen thought for a moment, then picked up his phone and turned on the camera...

Well!

There's no need to take a picture at all; through the camera, the area that used to have the apple's translucent golden outline is now completely empty!

If you move the phone away again, you can see the outline of the Apple logo again.

It really is invisible!

What surprised Li Lechen even more was that although the apple seemed invisible, he could still grab it by hand and put it in his mouth, where it was still crunchy.

Unfortunately, there was no mirror in the room. If there had been, Li Lechen really wanted to see himself crunching away while chewing "air".

Cough cough!

That's definitely a bit stupid.

After painting the apple, Li Lechen then dipped the brush in paint and started painting his water cup.

The water cup is a glass cup, and there is still half a cup of water inside.

After the paint was applied, it indeed became transparent.

I can still drink water from the cup, and it feels like nothing has really changed.
