The Great Reaction Race
Hot or cold, whole or crushed: which reaction wins the race?
Your students race real reactions, changing one thing at a time: temperature, crushed or whole tablets and the amount of bicarb. Choose three or four experiences, from lava lamps to exploding jellyfish and rockets, and we pitch every challenge to your stage.

What's In The Great Reaction Race?
A hands-on workshop about reaction speed: what makes a reaction go faster? Choose three experiences for 60 minutes or four for 90 minutes, and every pair works through them with a challenge card matched to your stage.
Every session opens with a surprise demonstration that gets the whole class asking questions, and ends with a spectacular finale. In wet weather, outside experiences move indoors.
