secret agent party for ds 7 - ideas anyone?

[Art]

I'm doing a party at home for ds (7) can anyone think of any games we can play with a spy theme. Traditional games would be great but I'm struggling to think of a spy twist for them.

Any ideas gratefully received

pin the dark glasses on the spy

treasure hunt using clues to solve

pass the explosive parcel (? )

a cross between what's the time Mr Wolf and musical statues where you have to try to follow the target and freeze as soon as s/he turns around

secret message writing (lemon juice and iron by adult?)

and this one pinched from another thread:

"If they start getting a bit noisy, get them all to sit in a circle. Choose one child to go in the middle blindfolded. Put some keys in front of blindfolded child. Adult then points to a child sitting in the circle. The child walks all the way round the outside of the circle back to their place, they then walk into the circle and try and pick the keys up without making a noise. The child with the blindfold can point in the direction if they hear any noises. It is then the person who was creeping to sit in the middle.

We played this at DDs party last week, it really worked well as most of them had never played it. The peacefulness of the game was fantastic! (Plus when all the parents arrived all DC were calm!)grin"

Invites written in lemon juice. If you warm the paper, the words appear (you may need to add an explanatiry note telling the parents to warm the paper! )

Leave them in a field with a map and goggles. The one who finds their way home wins a prize

hide and seek

hide letters round - find letters and put together to make a hidden message...you know your party tea is in the etc

pin the dark glasses on the spy

if it were warm a big water pistol battle

there are loits of films (cheating i know...)

pagwatch - goggles??

Thanks for ideas everyone - its not for a few weeks yet so hopefully the weather will be warm - Pagwatch I like the idea of leaving them all in a field

and I'll definitely have to try out the lemon juice!

Fingerprint everyone as they come in!
