On
this site you can discover some special formed lavabombs. The master of
creation is the air, so you can talk about a free aerodynamic design.
The high
ejected magma-shreds must leave the bocca very fast to get formed in the
colder layers of our atmosphere. Before landing the body must reach the
ground solid, not to get destroyed. An important point is also that the
flight-object should not carry too much H2O inside, and that the gases
have no time to leave the pyroclastic.
The
"lava-esthete UFO" maybe was shot at the feb.15.2000 over 1.5 km into the
atmosphere before he landed in my rucksack. Now you can see, that a lot of
facts are important to create this special form. This air- formed-bombs
are also very seldom.( More creations are following )
