Heat demonstration

Kids were amazed with convection demonstration today.

They went “wow” when they saw the red dye reversed its direction. Love their expression! If only I could snap a photo of their wide-eyed reaction. hahaa.. This is why I enjoy doing demonstration 🙂

The kids also had fun with a “magic liquid”.

They kept asking me where to buy it and I was like… I don’t even know what this “toy” is called to google to buy it.

Also did metal ball and metal ring, but not much excitement as these two demo.
