Okay so the other day in Biology class we were learning about hypotonic,hypertonic,isotonic solutions and how they react with another uhm..thing. so my teacher got a regular egg and put it in vinigar for 48 hours. then she rinsed it off, and got the white or brown stuff off. then you can like bounce it on the counter and it's bouncy. but don't bounce it to hard or to high off the ground cause it will break. then she put it in some corn syrup. and it shrunk! it was so cool! if you wann amaze your children or yourself, you should do this.
