Calculus All Night Long

hello, folks! well, last week I watched some videos on YouTube, and found some awesome videos!

Because of  I'll have a midtest next week, I wanna show you a very-funny-educative-video. Calculus Rhapsody! tadaaa..

fun, right? haha.

next, the most favorite video was a cover for All Night Long (Demi Lovato) by Mike Tompkins...

COOL!! I hardly believe it's no instrument!

I want to upload more videos but I don't think I have enough time hehe. so, 2 is enough :) Bye! have a nice day!
