I don't think there's anything remotely random about these kids, or the setting, or what's going on there. This is borne out by the fact that the trailer starts off with them, and spends a comparatively great deal of trailer time focusing on them and this incident (as opposed to brief snippets of random college students, bobbies, and townsfolk reacting to the arrival and presumed assault of Malekith's earthship or whatever in London).
The kids didn't get a "great deal of time" spent on them. They get less than 8 seconds face time.
That little shot is just showing the affects of physics on Earth as the "The Darkness" has shown up, ala Odin's commentary .... and those youngsters are just besides themselves as to what is going on. We also get to see anti-gravity when Jane is being held up in the air by Malekith and when his ship arrives.
It's not the Runaways man, I know you've suggested that quite a few times.
