The fair is a huge science expo designed to get young people interested in the sciences. There are stands as diverse as the new fastest car in the world attempt, the army engineers, a fully dissected pig and as many robots as a tech head could want. There were thousands of students present, even some exhibiting there own research, and they were loving it. Seeing so many inventive ways to bring science to life was awesome, even if there wasn't much biology. I suppose this is because most of the money in biology is to be made in biomedical fields, something that is really important but I just don't find enthralling.
The thing that blew my mind the most was a 40min show by the Gastronaut. He's a YouTube science communicator and together with his Quantum Mechanical Chocolate Factory they collide fairly high level science with food in an engaging way. Through food the explained crystalline structures, fluid dynamics, diffusion, UV and phosphorescence. Any teacher who wants to bring chemistry alive should check it out.

On this channel you can watch videos about how to extract iron from bran flakes, how to make dry ice and how to make your own chewing gum, all in your own kitchen. These are really cool experiments that can be transferred easily into the class room to make science fun for young kids. But even if you are not a teacher, just someone with small children or nieces and nephews, then these are fun things you can do to get children interested in science.
