Thank you for supporting us by commenting, it means a lot. As a lot of people said, we're now focusing on experiments, which students can make at home. A lot of fun facts also coming. I know we have promised to have a lot more posts, this time we will achieve that goal. If you like new posts everyday, just commenting below. Thank you for keeping up with up for the past few months.

 

Egg Geodge is a very fun experiment we found on the Internet. This is the video of how it works. Me and Chi attempted to do it at our home. It turned out quite well, another tip is not to put egg shells over egg shells. It won't work that way :D

How does it work?


Your egg geodge is formed through a process called sedimentation. The heated alum solution contains suspended particles of alum powder and as the solution cools, these particles of alum begin settling. When the alum particles settle towards the bottom of the beaker or glass, they begin crystallizing. With the alum-covered egg at the bottom, the alum particles from the solution begin attaching themselves to the egg. Covering your egg in alum powder beforehand gives the suspended alum particles a surface to which they can more readily attach themselves. The particles that settle onto the surface of the egg crystallize, and you will also see crystallization on the bottom and sides of the beaker or glass.

Best regards,
