Why is lycopodium powder flammable?
Concept: Lycopodium powder is made up of waxy spores from club moss. It was once used as flash powder in early photography. When the powder is squirted into a flame, much of its surface area is exposed to the oxygen in the air and is readily combustible.
Why is lycopodium powder sprinkled on water surface?
Lycopodium prevent to mix oleic acid in water, when drop of oleic acid is poured on water. So lycopodium powder spread on water surface first and then thin layer of diluted oleic acid is made on surface of lycopodium spread on water.

Is lycopodium powder hydrophobic?
The powder is also highly hydrophobic; if the surface of a cup of water is coated with lycopodium powder, a finger or other object inserted straight into the cup will come out dusted with the powder but remain perfectly dry.
Is lycopodium the same as Lycopodium Clavatum?
L. Lycopodium clavatum (common club moss, stag’s-horn clubmoss, running clubmoss, or ground pine) is the most widespread species in the genus Lycopodium in the clubmoss family.
What is diameter of lycopodium powder?
L YCOPODIUM powder is a natural organic product composed of ∼30 μm diameter unicellular spores [1], [2] from the common clubmoss (fern) family Lycopodiaceae.
Can lycopodium powder get wet?
The adhering powder can be shaken off on the surface of the water. As long as enough powder is kept upon the surface of the water, the immersion can be repeated over and over again. The flnger will neverbecome wet.
Why is lycopodium powder hydrophobic?
Since these spores are only single cells, it also means they are quite light. The reason they are hydrophobic is to keep the powder as light as possible so it can travel by the slightest of breezes.
What is the size of lycopodium spore?

It is usually erect (e.g., L. selage) or pendent (e.g., L. phlegmaria) in the sub-genus Urostachya and prostrate creeping in the sub-genus Rhopalostachya, which is sparsely (e.g., L. annotinum) or profusely branched (e.g., L.
What is Lycopodium powder made of?
Lycopodium powder is a fine yellow powder derived from the spores of Lycopodium clavatum (stag’s horn club moss, running ground pine). When a lighted match is dropped into a pile of this powder, it does not burn. However, when the powder is dispersed into a fine mist near a candle flame, it ignites into a spectacular fireball.
Is Lycopodium flammable?
Lycopodium powder is flammable when dispersed into a fine mist. Usually, with this procedure, the flame burns out too quickly to light any other combustible materials, but caution should be exercised nonetheless. Explosions of Lycopodium and Other Powers: Bassam Z.
