..🕹| This is a total waste of time, but I can't stop playing!

So I found this weird tube looking thing on the internet that you manipulate with your mouse (or finger on a smartphone) and it's completely dumb, but it's strangely addicting. Try it for yourself!

Also, If you shake it 'vigorously' even stranger things start to happen. 

If you tried it, what do you think? Sound off in the comments.
