Do tea lights float in water?

The tea lights can float in water. Because of the small size and shape, it doesn’t weigh that much. Rather, it displaces more water than its weight. The weight of a candle gives equal force to the buoyant force. That’s why, it manages to stay afloat maintaining its balance in the water surface.

Normally, the size of a tea light is 2”-3” in diameter. The shape of a tea light is mostly flattened in the bottom. It can be slightly curved in the top, flat in the sides, round in shape with a plain design.

The shape helps mostly to keep it afloat. If the sides were made round, the candle wouldn’t be stable in the water. Again, if it had a flat top, the water would come to the surface easily. And it would turn down the flame.

Moreover, its density is smaller than the density of water, which also supports. It’s specially designed in this way that it can displace more water than its weight.

When it’s placed in water, the weight of the candle gives more or equal force of the buoyant force. These scientific facts help a tea light to float in water and maintain its balance.

Density:

The density of the water is greater than the density of the candle’s body.

Water Displacement:

It’s made in such a way that the candle’s body can displace equal or more water than its weight.

Weight= Buoyant force:

The weight of the candle’s body is little. And it’s equal to the buoyant force. It helps the candle to be stable in the water.
