This is interesting. Don't you risk the 'Eureka moment' being something that's not important? I wonder if one could, as a teacher, manufacture this with seemingly nonsensical one-liners that eventually become clear. I sort of do this with my kids, dropping titbits to try and entice interest: "of course we are time travellers, moving at a second-per-second most of the time" but that could be more explicitly tailored to "... except under time-dilation". Perhaps the latter gives a hook "time dilation" to hang the concept on later when it's learned -- maybe like reserving disk space when downloading a large file. Or perhaps it's the 'transfer' of the concept to the hook, at some point, that makes for a 'repitition'.
