Produce a spectacular fireball by sprinkling milk powder over a flame and witness how an increased surface area can also increase reaction rates.
A pile of dried milk powder will not ignite even if a roaring Bunsen flame is played onto it. However, if the powder is sprinkled onto a flame, a spectacular fireball is produced which demonstrates the increased reaction rate by increasing surface area.
