For school science fair? I was thinking something like the CANDU reactor?
The best insulation, and most expensive is Spray foam
If u read the instructions on the new alarm it will say the life of the alarm is usually five or seven years. Most alarms have radio active switches than send a signal to the other side of the switch saying nothing is interfering with the circuit. If smoke gets between the radio active switch, the alarm will notice the interruption in the circuit and will sound the alarm. I buy the combo smoke and carbon monoxide type that is voice activated. Fire Fire shouts the nice female voice. Or Carbon monoxide Carbon monoxide shouts the lady.
Fiberglass insulation has been widely used to insulate buildings. It is simply a collection of millions of tiny shards of glass, one simple tap will expel tens of thousands of microscopic particles into the air. These particles can often end up in carpet, clothing and heating and air ducts. This is why it is so important to make sure that not even a little fiberglass insulation is exposed, especially in a place like a basement where people often do laundry and where heating and air ducts tend to run. It appears that fiberglass insulation is safer than asbestos, which was widely used in the past and later found to be responsible for health problems like malignant mesothelioma and lung cancer but all the facts about the toxicity of fiberglass insulation are not known. This is just one of the reasons why Radiant Barrier Foil is quickly becoming the 1 choice for building insulation. You can apply it over the fiberglass insulation for double the energy efficiency. Radiant Barrier Foil is a lightweight, reflective material made of a plastic substrate with a vapor-deposited coating of aluminum. It was developed by NASA to insulate astronauts during space travel.
