  1. FLOTORUL Materiale: -un tub sau un pahar inalt de sticla cu apa -o cutie de medicamente care sa intre in tub -cateva saibe sau greutati rotunde de fier

  2. Punem in tub sau pahar apa ca in imagine si punem dedesubt un vas de protectie.Gaurim capacul cutiei cu ajutorul unui ac sau al unui compas facand o singura gaura de dimensiunea acului

  3. Saibele sau greutatile alese trebuie sa aiba aprox. diametrul cutiei. Introducem ca in imagine greutatile astfel incat atunci cand lasam cutia in apa ea sa stea la nivel.

  4. Exercitand presiune asupra tubului observan ca pe gaura facuta in capacul cutiei incepe sa intre apa si aceasta sa se scufunde. Este foarte important ca atunci cand cutia se afla la suprafata apei, paharul sa fie plin ras cu apa.

  5. Proiect realiyat de catre Dordea Filip,Török Andrei si Deac Ovidiu din scoala Radu Stanca sub cordonarea prof. Aneta Surducan.
