Simulation of the greenhouse effect with silvered and unsilvered glass bottles.
What it shows:
Heat energy readily escapes from a clear glass flask, but is trapped inside a silvered flask which rapidly heats up.
How it works:
Two 2L flat bottom Florence flasks, one clear and one silvered (see reference), have identical 10Ω, 25W resistors placed inside them connected in series to a DC supply 1 These resistors act as good sources of infrared radiation. The clear flask readily transmits the IR, but the silvered...
