Show I Scientist Makes S Soap Sap ap Bubbles That Last a Year I When scientists run out of their or ordinary ordinary or- or occupations they look around for tor something new to do One of the very very newest oddities worked out by scientific experimentation is the blowing blow blow- ing big of a soap bubble that will last a whole year before breaking Apparently Ap Ap- ApI Ap- I that is achieving the height of useless effort but Prof J. J Dewar I of London expects to prove pro a good I many things thing's b by this curious method In a recent address before the royal institution he exhibited a number of small soap bubbles that were 12 months old lIe He also showed bubbles hubbies more moro than half halt a aard yard ard in diameter which had grown to the hoary lOary age of 6 G months These bubbles hubbIes w were re confined confined con con- fined in glass containers that had been pumped free tree of air thus creating a vacuum for lor the tho bubbles to rest ret in Professor Protessor Dewar said that it was necessary ary to obtain air ail free of dust to make a soap bubble that would endure I for more than a few seconds second To do 10 I this he developed several appliances that take all an the dust out of a limited air space and it was by the use of this air that his marvelous soap bubbles bubbles bub bub- bles were blown But further effort was necessary to preserve these bub hub bles It was found that tho the few drops of water which always gather at the bottom of a Q bubble were fatal to their attaining a respectable ago age So the professor applied little tubes to the bottom of ot the bubbles much like a soda foda water straw and drew the water off As a task for patience this is recommended recommended rec rec- to the Impatient I The remarkable soap bubbles of this educator are preserved in glass vessels vessels ves yes sels eels having a little water In iii the bot bot- tom torn The temperature of these vessels ves yes ads sels Is maintained at about 50 EO degrees Fahrenheit Several years were taken up UI by Professor De Dewar ar in finding out I all about soap bubbles and he la is now nov working ng- ng ngon on a plan connecting them I with atmospheric changes chang |
