Autumn scavenger hunt

Organ tabard

Two-coloured invisible ink

Colourful Autumn leaves

Food colouring fireworks in a glass

Making the bath fizzy

Extinguishing fire

Making malachite on copper coins

Glowing in the dark

Less messy colour-changing turmeric painting

Colourful milk and washing up liquid

Making secondary colours appear and disappear with oil and water

Birthday balloons
