Balunakahi ʻāpana lahilahi o ka latex e like me ke ʻeke liʻiliʻi. Hoʻonui ʻia nā baluna me ka helium a i ʻole ka ea, akā no ka mea he pipiʻi ka helium a ua hoʻoheheʻe koke ʻia nā baluna helium, ua hoʻonui ʻia lākou e ka waha a i ʻole ka paila. Makemake nā keiki a me nā mākua e puhi i ka baluna no ka hoʻokuʻu ʻana i nā endorphins, ʻo ia ke kumu e puhi ai lākou me ko lākou waha. I ka makahiki 1824, ua haku ʻo Michael Faraday, he polopeka ma Queen's University, i ka baluna palaki no ka hoʻohana ʻana i kāna mau hoʻokolohua me ka hydrogen ma ka Royal Institution ma Lākana. ʻOkiʻoki ʻo ia i ʻelua ʻāpana ʻōpala, kaomi i nā ʻaoʻao, a uhi ʻia i loko me ka palaoa i ʻole e pipili. Ma mua, ua hana ʻia nā baluna mai nā ʻōpū holoholona. Ua kūʻai ʻia nā baluna pōpō mua i ka makahiki 1825, akā ʻoi aku ka nui o ka hoʻokolohua ʻepekema ma mua o kahi pāʻani. Ua hana ʻia nā baluna Latex no ka manawa mua i ka makahiki 1847, i hana ʻia me ka latex rubber vulcanized i ʻohi ʻia mai nā kumulāʻau hevea brasiliensis. Ua manaʻo nui ʻia ʻo ia nā baluna hou mua loa, ʻaʻole pili i ka mahana a me nā mea pāʻani maikaʻi loa. I kēia lā, hana ʻia nā baluna mai ka ʻōpala, ka latex, polychloroprene, a i ʻole ka lole nylon, a hana ʻia i nā kala he nui.
