Chill the water in two plastic bottles (for example, in the refrigerator). Then take out the bottles, put one of them on the table, and wrap the other in a warm blanket. Check after a while: has the “warm” blanket warmed the water in the bottle? Draw a conclusion from your experience.

An unwrapped bottle will heat up by taking in heat from the environment. A bottle wrapped in a blanket will remain cold, since the blanket contains air between its own curtains, which is a poor conductor of heat, so heat will not flow to the bottle.
