You know those sugary marshmallow cereals, like Lucky Charms? You can buy just the marshmallows online, but they’re expensive: about $10/lb.

The local super market has a cheap generic marshmallow cereal, available in bulk at $6.49 for 38 ounces.

You know where this thread is going.

I bought some and separated some of it. Result: 1.4 oz of marshmallows and 5.76 oz of non-marshmallow. So the cereal is a bit under 20% marshmallows.
