It depends on the individual. I spent the majority of my early teens disassembling binaries and writing programs to patch software, reading virus source code and trying to wrap my head around polymorphic viruses, manipulating acid/base/oil to make soap and metals to produce gas and currents and observe surface phenomena, distilling plants and flowers to make oils, trying to understand programs to simulate forces on an airplane, lockpicking, perfecting copper tube-lead-match firecrackers, making darts that fly go relly far. Super, super fun, right? My nephews and nieces wouldn't do that if I paid them. This is mainly due to the fact that I don't know how to teach them and I didn't invest time in learning how to connect with younger people. I'm watching this thread for ideas. I'm considering "Physics for Everyone" by Landau and Scratch for which I have an apprehension because why learn that when I know they're capable of learning to code directly, but maybe it would help getting them hooked.
