Ever wondered how much energy it takes to make a simple cup of tea?

Probably not, but that's exactly the reason we developed our brand new Extreme Tea Energy Challenge. In a head-to-head challenge, two people battle it out to demonstrate just how much power a human needs to generate to produce the energy required to boil an extremely small amount of water.

Educational and highly competitive, it's a fun and engaging activity that is suitable for adults and children.


A scale of temperature runs between two LED light tubes acting as giant thermometers and the challengers go head-to-head in an attempt to see who can reach the highest temperature in a given time.

Two Power Monitors display the real-time power output of each cyclist or team and records the maximum watts achieved and highest temperature reached. Each cyclist or teams temperature is then recorded on our 'top gear style' Magnetic Leaderboard and new challengers are encouraged to try and better their attempts.
