science museum wallace and gromit - is it free for under 5s (or under anything?)

[muffle]

I can't tell from the website - it just says children/concessions £7. Does anyone know if there's an age below which children are free?

TIA

Is this in London? (nosy)

Yes - though we're not in london so we're going there for a long weekend and I should probably book for this in advance.

(It's a special exhibition of W&G's inventions btw)

If you click through pretending you are buying a ticket, the (shoddily designed) website reveals that children aged 4 and under are free.

If you have a toddler make sure you go to The Garden in the basement to splash about in the water feature and play with bricks and wheelbarrows. That's free, and ace. And you can eat your picnic there too.

Oh thank you wobbegong!
