Submarines in Medvode (Slovenia)

V podmornico smo stresli nekaj pecilnega praška in počakali, da je z vodo reagiral. Ustvarili so se mehurčki CO2, ki so povečali vzgon podmornice, ki je zato izplavala.

 

We put some backing powder and wait to react with water. Appeared some bubbles of CO2 which increased buoyancy of submarine.
