Last year, my team studied boat wakes in relation to bank erosion. We got to the final but didn't make it to the top prize. Hopefully this short clip will make you laugh!

I entered teams into this amazing competition in 2022 and 2023 (working with two different schools.) I also visited the Water Week Conference while on holiday in Stockholm last summer to check out the global entries. I don't have an entry this year but have got two high-ability14-y-o students who have started a pollution project that we'll probably enter in 2025. 

My feedback - this is a great competition, but the time commitment means that it's best suited (IMHO) to the non-examination years - Y10 and Y12. The standard is high and it's focused on individuals or pairs only. Our other STEM competition work this year involves much larger numbers of students with a broader range of abilities.

Having said that, the top prize is amazing! There's nothing else like it.
