Rasgulla. Rasgulla (literally "syrup filled ball") [a] is a syrupy dessert popular in the eastern part of South Asia. It is made from ball-shaped dumplings of chhena dough, cooked in light sugar syrup. This is done until the syrup permeates the dumplings.

Capillary action of water (polar) compared to mercury (non-polar), in each case with respect to a polar surface such as glass (≡Si–OH). Capillary action (sometimes called capillarity, capillary motion, capillary rise, capillary effect, or wicking) is the process of a liquid flowing in a narrow space in opposition to or at least without the assistance of any external forces like gravity.
A chemical bond is the association of atoms or ions to form molecules, crystals, and other structures. The bond may result from the electrostatic force between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds, or some combination of these effects.
Bengali (বাংলা Bangla) is one of the Eastern Indo-Aryan languages, which evolved from Magadhi Prakrit, native to the eastern Indian subcontinent. [1] The core of Bengali vocabulary is thus etymologically of Magadhi Prakrit origin, with significant ancient borrowings from the older substrate language (s) of the region.
