GlowPals
Red light and green light make… yellow! Guess what two coloured lights make, then slide the glowing gels together on a light table and see. Light adds up, paint takes away. Then make your phone a steady red or green light and make coloured shadows in a dark room. Ages 6–8.

Meet the cast
GlowPals's friends carry lights. Glowby the firefly mixes them, Rubra glows red, Leafen glows green, and Bluet glows blue. Together their light adds up to white.
Glowby
shines two lights on the same spot and watches them add up
Rubra
A fox with a red lantern - red light, which with green makes yellow
Leafen
A tree frog with a green lantern - green light, which with blue makes sky blue
Bluet
A jellyfish with a blue glow - blue light, which with red makes pink-purple
