Ideas for the make £5 grow project please.

[amethyst123]

Please can anyone share any ideas for the make £5 grow project? DD and I have been trying to come up with cheap ideas but a lot of them are already being done and her teacher wants her to come up with more original ideas over the weekend. We can't use food unless its fruit due to unhealthyness so can't make cakes or use sweets. The ideas we have come up with so far are:
Decorate balloons with faces and hair
Decorate rocks
Decorate pens with googly eyes and hair
Make keyrings
Make badges
But like I said a lot of these are being done already so we need some new ideas and I'm really struggling to help her.

Photo booth. Spend your £5 on props and then charge for people to take photos on their phones.

The girls made slime & made a lot of money.

Nails painted was popular too

Shame about food as popcorn is a good money maker!

NOt balloons please. So bad for the planet. Other than that I've not got much. Friendship bracelets? Some great tutorials online. Macrame hanging baskets? Grow herbs?

Some great ideas thank you, sorry I didn't think about the balloons being bad for the planet I will scrub that one from the list. I like the nail painting idea and the photo booth one although I don't think they can have phones till the end of the day and I'm not sure if the sale will take place at break times or not. Anyway I'm off to google 'How to make slime'
