Description
This week's challenge is to find a way to detect radioactive rocks and flammable gases. On day three they must explore a wet dark mine using the gas detector and a reliable light source. Hermione... decides to make a cloud chamber using a jam jar. She hopes to see the trail of destruction caused by radioactive particles. First, though, she'll need to make some frozen carbon dioxide which involves a bit of help from Mike. Mike and Ellen work on a safety lamp to detect flammable gases, which surprisingly needs a flame. Ellen sets off to make a beeswax candle using a local hive. Meanwhile Mike finds an ingenious way to use the candle flame as a gas detector using kitchen implements. Will two artfully put together sieves and some homemade beeswax candles really detect flammable gas?
