Make a harmonica

Try this simple experiment at home to make your own noisy harmonica using the science of vibration.


Fireworks get their colour from different metals mixed in with the gunpowder, which burn brightly when ignited.


There are 100,000 miles of blood vessels in an adult human body. If you laid them end to end, they would stretch around the Equator twice.


The Eiffel Tower in Paris is 15 cm taller in the summer than it is in the winter due to thermal expansion. It is engineered with special ‘expansion points’ to allow it to grow larger in the heat without damaging itself.
