They develop strange, twisty shapes, grow horizontally, branch or otherwise behave weirdly. No-one is really sure how, and of various theories, some may apply to some helictites but not others!
I have seen one form, in one cave and one only as they are all unique, resembling something from a Mediaeval church. They were only about 20mm high, each consisting of a thin straight stem with a little cross-arm. The three tips each held a tiny, exquisite "botryoid" (a cauliflower-like formation) no more than 3mm across. Unfortunately none of us in out team photographed them.
I have also observed "outdoor" helictites - actually inside a building. These tiny examples are growing outwards from a ball-valve maintaining the level in a laboratory tank, and resemble little, pure-white whiskers up to 3mm long.
It seems there may be a misunderstanding. "Stalacities" is not a known term. Stalactites, however, are mineral formations hanging from the ceilings of caves, formed by the deposition of calcium carbonate from dripping water. Let me know if you need more information on stalactites.
They are different from regular parks because regular parks have playground equeptment.
First you must define what regular is! Regular means what? Regular coffee has cream and sugar to me, but if someone drinks black coffee, is not their regular different from my regular?
Jumbo mortgage rates are different from regular mortgages in several different ways. Jumbo mortgage rates differentiate from regular mortgages by having a larger payment due.
An electromagnet is different from a regular magnet because it can be turned on and off by controlling the flow of electricity through it, while a regular magnet is always magnetic.
Period blood is different from regular blood because it contains a mixture of blood, tissue, and mucus from the lining of the uterus. It is typically darker in color and may have a different consistency compared to regular blood.
A regular pentagon is both equiangular and equilateral.
How are "what" different from regular nuclear reactors? The question has insufficient information in it to be properly answered. Please restate the question.
There are different formulae for different shapes.
Each body has its own centre of gravity. The centre of gravity of two regular shapes - an equilateral triangle and a square will be different so why should the cog of a regular and an irregular shape not be different?
No, a regular tessellation uses multiple copies of only one regular polygon.
Yes
