The M69 was a plain steel pipe with a hexagonal cross section in diameter and long. It weighed about . The bomblet used napalm (jelled gasoline) as an incendiary filler, improving on earlier designs which used thermite or magnesium fillers that burned more intensely, but were less energy- and weight-efficient, and were easier to extinguish.

Ucuhuba seed oil Ucuhuba seed oil Ucuhuba seed oil is the oil extracted from the seed of "Virola surinamensis" (ucuhuba). The ucuhuba tree is found in Brazil, Costa Rica, Ecuador, French Guiana, Guyana, Panama, Peru, Suriname, and Venezuela. Its seeds provide oil rich in myristic acid. The ucuhuba oil contains 13% lauric acid, 69% myristic acid, 7% palmitic acid and traces of oleic acid and linoleic acid. Myristic and lauric acids comprised 91.3 mole % of the total fatty acids. Although additional saturated fatty acids were found (decanoic acid, palmitic acid, and stearic acid), they occurred only as minor components. Small amounts of
