Duplo custard

Recently we showed the children the fascinating properties of custard powder, is it runny or solid? Somehow this lead to a discussion of walking on custard.

Alex especially was very impressed with the clip of Braniac, showing John Tickle walking on custard  and has asked to watch it repeatedly.

Today he called me up to his room to show me his duplo model 

One swimming pool full of custard and John Tickle ready to dive in. There are even two lifeguards!
