The multifunctional tea infuser is in the shape of a bobber form. The device has two components. The first component is the upper part of the tea infuser. It serves as a caddy spoon to ladle out tea. On the handle of the caddy spoon, it has tea density scales. When the tea infuser is used to make tea, it will gradually sink in water when the tea leaves inside the tea infuser are stretched. One can read the scales on the rod of the tea infuser to determine the concentration of the tea. The second component includes the lower part of the tea infuser with a short balance metal rod which is used to keep the tea infuser in a vertical still position during tea making.
