I wondered why he put aluminum foil under his table legs ...?

Now that we know we have to avoid cooking with aluminum foil because it's carcinogenic, we tend to not use it ... Yet it's very handy to use anywhere in the house.

When moving a piece of furniture, place aluminum foil under the table legs. This will prevent you from making marks on the floor and your furniture will be easier to move.
