Diving Warheads

Warheads sink. Air bubbles float. A Warhead inside an airtight wrapper does both...if you squeeze it hard enough to compress the air bubble. This makes the candy wrapper package denser than the water, and it sinks. But if you release the bottle, the bubble expands and the candy floats again! You've made a Cartesian diver.

To make a Warheads diver:
  • Open a bottle of water and push the wrapped Warhead inside.
  • Make sure the Warhead floats. If you put it in the bottle and it sinks immediately, try another one. (Some Warhead packages don't contain enough air to float, or have holes that let water in.)
  • Fill the bottle completely full, so that there are no air bubbles at the top. Any extra air bubbles will make the Warhead harder to sink.
  • Screw the bottle cap on tightly, or you'll send water shooting everywhere!

You can also try this with ketchup packets or other items that trap air bubbles.

Lucky Charms, Sugar, and the General Mills Journey

General Mills is on an exciting journey to be responsible and give back.

Apparently, "That's why Lucky Charms Has... 10 g of sugar per serving."

Written in the finest marketing speech, this sounds like bragging. But it's not. Since a serving size is only 27 grams, this cereal is 37% sugar.

That's like eating eight nickel-wide Smartie candies.
