WHY can we carry no more than 100 ml of liquids in a hand luggage?

It turns out that the "100 ml" rule has been in effect at European airports for more than 12 years.

This rule first appeared in Europe after an incident at a British airport — police arrested a group of criminals with liquid bombs.

It was then that it was considered liquids in containers of up to 100 ml and a total volume of up to 1 l do not pose a threat — roughly speaking, with that volume of flammable liquid on board, a dangerous ignition is unlikely.
