This was another experiment from our science curriculum. (I try to always do the experiments!) If you light a nut on fire, it will keep burning because of all the oil in it. These burned a minute or longer. As always, I cautioned them to be careful and not to do this at home.
And, when your almond is done burning, it makes a good charcoal pencil.
