Designing a boat

When we were in Istra we did a lot of investigations and also some fun activities too.
One of them was designing a boat so that it can move because of chemicals we put in it and not sink.
My partner was Natalia Smolenova,  we shared ideas and helped each other in designing a nice boat.  Our boat looked like a cutter,  we well balanced it so that it will not sink in water and made a propeller like structures on each side of it where we also made hall.  So that the co2 from chemicals that we put in can escape and make the boat to move.  Our experiment worked very well:)

 Yes that's our boat:) 

By doing this activity i developed new skills,  undertook new challenges as I never made boats,  which didn't sink on water and actually did move.  I also showed perseverance and commitment and worked collaboratively with Natalia.
I enjoyed that activity because our boat did move.
