When Tiger came across something that looked interesting, we carried out an investigation:
The instructions for the "bouncing eggs" experiment were simple enough. Just soak an egg in vinegar for 24 hours, then it is supposed to be able to bounce.
|3 minutes into the experiment.|
|24 hours later.|
It didn't work!!! How annoying! After we got past the initial shock of the unexpected result, we found the reason why from this website that has a more detailed and clearer explanation to the same experiment: the egg has to be left in the vinegar for 72 hours or longer, until the outer shell has been totally dissolved. Wrong instructions from the initial book, then.
