If you are stuck for something to do whilst waiting to get into the the Kylie exhibition in the V&A, then head across the road to the Science Museum it was very good and we only go to see 1 floor. Don't go on the weekend unless you have to, cause it's full of kids, not a bad thing in it's self just you'; have to queue up for all the good stuff! Will defo head back there! Dad you'd love it.
