  • $ 33.77

Use our Convection Box to demonstrate the flow of convection currents in a gas. Place a small, lit candle under one open chimney, then use touch paper or a wood splint to introduce smoke into the opposite chimney. The heat from the candle will cause the air to flow and the smoke to travel down into the box and back out the other chimney, showing a convection current. Instructions included.
