Hi cruch labs
This whole video should have just been reduced to only that first video with the binder clip. 😄
i tricked my uncle with the spider box and it took him 5 whole minutes to figure it out. he didint ever figure out the mirror! and then he screamed like a little girl!
If this had been around when I was a kid, 2 terrible high school science teachers wouldn't have made me avoid science in college.
8:21 For those who dont understand how it works, here's an explanation:
There is a mirror inside the box and when u put a coin inside it goes to the backside which u cant see.
hope this helps
