Charity Challenge Donate Fundraise Charity Challenge Any fun activity to get the grey matter working. Encourage your friends or work colleagues to bring in a picture of themselves as a baby or child and post them up on a board. Charge a pound a go to guess who’s who. What about holding a quiz night at your local pub or karaoke sing off session? Try to guess how many sweets are in the jar – winner takes all. Arts and crafts are always popular – card making, flower arranging, decorating ceramics like cups, plates and vases. You can approach local art suppliers and shops for free materials. Just charge a small fee to take part.
