Poti incerca obtinerea de H (hidrogen) care e mai usor ca heliul dar in schimb e f usor inflamabil. Se obtine usor cu acid slab + metal puternic reactiv sau acid tare+metal mai slab reactiv sau acid tare + metal puternic reactiv. Poti incerca diferite reactii (daca apar bule e bine; da foc deasupra acidului si vezi daca arde). Eu am utilizat otet (acid acetic) cu magneziu si a mers super. Am pus intr-un PET de 1/2 l otet + Mg si am pus un balon pe gura sticlei. Se umple rezonabil cam intr-o ora 2. Mai repede merge cu acid sulfuric sau clorhidric + magneziu. Nu stiu daca se gaseste asa usor magneziu sau cat de scump e (eu aveam prin casa :d).Mult noroc.
