Can you guess how they made these objects invisible underwater?

Prepare to get your mind blown: Japanese scientists at the Euphrates partnered with Japan's National Institute for Materials Science (NIMS) and has brought this amazing Rube Goldberg machine demonstration to your screen. Don't forget to open the subtitles!

You may be asking what a Rube Goldberg machine is. Well, a Rube Goldberg machine is a machine that is designed to perform a relatively simple task in an overly complicated way, perhaps with a complex contraption. Dominoes are a perfect example of that.

In this case, you'll actually see glass ramps, stairs, and dominoes disappear into the thin air. You might think that you're seeing some clever editing; however, that's not the case at all. It is actually about the oil being adjusted to match the glass' refractive index, but you'll need to watch the video for detailed information. 

Did this video get you interested in conducting experiments of your own at home? Well, you could always check out these fun experiments to get started.
