dash of liquid, and acts like a springy solid? The answer is foams.
Foams are so common we seldom appreciate how strange they are. In fact,
much of what is known comes from trial and error. There are even
metallic foams that can be shaped into antennas for radio transmission
and reception. . Because of this and other high tech uses, the precise
stiffness of a foam is crucial for many uses.
At the moment, no theory currently exists for predicting exactly how
stiff or oozy a foam will be based on its traits like the size of its
bubbles or the amount of liquid it contains. But scientists are
designing an experiment for the International Space Station to
investigate the puzzling physics of these everyday substances. You can

DX
In D-X, word that M5BXB will be active as OK8XB from the Czech Republic
through the 27th of December. Look for him on 20 and 17 meters during
the day and 40, 80 and 160 meters at other times. He also plans to be
active on 2 meters from a location 1,323 meters above sea level. And oh
yes. He promises to present a festive bottle of local Plum Brandy to
the first U-K station worked on the 146 MHz band. (RSGB)

THAT FINAL ITEM: A HAM RADIO CHRISTMAS POEM
And finally this week we want to leave you with a bit of ham radio
holiday cheer. Here's Gary Pearce, KN4AQ:
--
'Twas the night before Christmas,
And all through two-meters,
Not a signal was keying up.
Any repeaters.
