100th birthday scavenger hunt

[Thorilicious]

My lovely nan is 100 in a few weeks, and we're organising a party for her.
I'd like to organise a scavenger hunt for the kids, to help keep them amused..
So far I have
Find a coin with her year of birth on it
Write a message in her guest book
Have a photo taken with her

Any other ideas please? It's being help in a bar, and can be aimed at adults too. Thanks in advance.

Have 3 old photos and ask them to guess which one is her.

Headline from the newspaper when she was born - ask them to write what they think it is about.

What? A coin with her year of birth on it? How?

Yeah, there won't be a coin with her year of birth on it- unless you are planning on hiding one?
How about 'find a coin with your own year of birth on it'? That should get them rooting through a the grown ups bags and pockets!

This is an amazing idea btw. Make her favourite sandwich or drink? Find a fact on the internet about something that happened on her birthday and write about it in the guest book?

Solve a 100 piece jigsaw puzzle
Find objects beginning with the same letter as her name
Build a structure with 100 cups
Calculate what year it will be when they turn 100 years old.
Give them an Argos catalogue and an imaginary budget of £100 and they. An make a list of what they’d buy. They’ll probably need a calculator!
Make a list of 100 fun things to eat!
String necklaces with 100 beads or Cheerios.
Read the 100th page of a book to an adult
Everyone gets a bag of 100 Lego bricks and they have to build something with the pieces that are in the bag. They have to be creative. They are allowed to trade pieces with each other if both parties agree to the trade.
Make a paper chain with 100 loops

@Rainbowunicat that's a much better idea about the coins!
Loving these ideas, thank you!

Bumping for more ideas.

Snapchat silly picture with gran?
Photos of ‘guess what we used this for’ such as a mangle?

Take a photo with three/four generations in?
Find a 'memory' someone has of each decade of the last century (they could collaborate on this so your nan doesn't get overwhelmed)

How about guess how old great-nan was when...and make a list of things like first had an indoor loo, first got a TV, mobile phone etc, left school. You might have to estimate a bit on the years as she probably won't remember exactly.

If possible, get them to do a family tree to include nan and themselves.

Ask them to draw a picture of nan, which you could maybe put in a scrapbook for her.

This is a good cryptic one. (Possibly needs adult input.) Collect something that dogs do.
Despite any yucking and giggling it's not gross. Because dogs ..... bark.

Loving the idea of "what did we use this for"....

And on a similar theme, what about a true or false quiz - e.g. "in the 1920s we lived in black and white" T/F "In the 1920s we still mainly used gas to light our houses" etc
and
older objects and their modern day equivalents - guess/link the photos
and
the equivalent amount that things cost then and now

I love Mumsnet, you've made my job so much easier. These are all fab, especially the 'bark' one
