Well the Cambridge Science Festival turned out just fine. The boys went and blew up rockets , made faces at robots and discussed quantum physics and I pottered around Cambridge.
I was very restrained and only purchased four old flower pots two punnets of strawberries and four small green and gold plates from Oxfam and two silver plated candlestick holders from another charity shop. Oh and a large disco ball! I think pre teen is getting that. It really was very enjoyable.
