 "But in a way mathematician is correct for that too - modelling oceans is really a mathematical science" says Mr Spring. The most way out are funeral director, undertaker and grave digger, and Mr Spring likes them for that reason. Therefore, we decided to give additional prizes to MAGDALENA CYRAN and PAUL KODUR. Congratulations!
We will contact our winners very soon!

Thank you all for funny guesses! We loved them all! :)
