- an empty salt carton
- a plastic sandwich bag
- a rubber band
- a lit candle
- Have an adult light the candle. Meanwhile, carefully remove the metal spout from the salt carton, and cut the bottom out.
- Stretch a plastic sandwich bag over the hole in the bottom, and use the rubber band to hold it in place, so it looks like a drum.
- Aim the hole from the spout at the candle flame, and tap the plastic bag from behind. Look at that! The candle flame is blown out!
From how far away can you blow out the candle with the air puffer?
