Cost: £25 admits one child and an accompanying adult. Call 020 8409 4400 to book your place.
It's a classic for a reason!

Cost: blissfully free

A particular highlight is Punk Science, talks which combine scientific insights with comedy (yes, really!) and live experiments with plenty of audience participation.
Cost: free! (What are you going to spend all this extra dough on, eh?)
