Flying reindeer

My sister-in-law bought this for my wife some time ago. It comes out at Christmas and with the right amount of heat beneath it, the turbines turn and the reindeer go round at with gusto. Last year it came out and didn't work very well, this year I realised that the tip was missing and there was too much friction to allow it to spin, so I made a new tip and it works more or less okay.
