Toma si Eugen fac experimente cu baloanele.

Astfel, ei descopera ca pot ridica o greutate de 50 de grame folosind 5 baloane mici umplute cu heliu. Trei astfel de baloane, dar umplute cu hidrogen, ridica 60 de grame. zece baloane cu neon ridica 20 de grame.

Cate grame pot ridica baietii folosind 5 baloane cu neon, unul cu hidrogen, si doua cu heliu ?
