Fourth Challenge

Verónica, Carlos, Xabier, Iván, María, Iñaki, Tania have given a valid answer for Romeo's Challenge. Congratulations!! :D These are some of your solutions:

And your brand new challenge is the following:

The Gallons’ Problem

Imagine the following situation: a bomb is set in Taconera’s Park and you are the only on capable of dismantling it. Spanish CSI Special Agent  Euler Piruleta requires your services and you find yourself before this bomb…

Only 4 minutes are left before the bomb explodes and the only way of stopping it is placing a bottle filed with 4 gallons of water in a balance. You have a 3-gallon and a 5-gallon bottle and a fountain with a continuous stream of water…

How can you get those 4 gallons inside one bottle using the 3-gallon and 5-gallon bottles?

Remember: our future depends on you!!! :D

Dedline: October the 31st! Do not forget to post a comment if you discover the solution  ^_^
