My mum used to put these magic crystal trees in our stockings and my sister and I thought they were brilliant. I've put them in my DDs' stockings on and off over the years, and they've loved them too, but wondering if there is something similar - a cheap kind of novelty thing or mini game that is a bit unusual.
Their stockings are stocking size, not massive sacks, so it needs to be quite small! DDs are 12 abd 15 YO, but something silly and childish is fine (they've got other more age appropriate stuff in their stockings too!).
Any ideas?
