Underwater rangoli

The procedure to make under water rangoli -

You could use a tray or a broad plate to make this rangoli. Apply oil or ghee on the surface of the tray/plate and draw the rangoli/design. Leave it for five to ten minutes ( for the rangoli to absorb the oil). Pour water slowly along the edges of the tray. The design would still be intact and you could reposition your tray according to your choice.
