Because they have a lighter density than water. However, in some other liquid a poppy seed might sink because of having heavier density than that liquid.
Orange seeds float in sugar water because the sugar increases the water's density, allowing the seeds to float. In ordinary water, the seeds sink due to their own density being greater than that of the water.
Calamansi seeds have a lower density than sugar water, causing them to float. In ordinary water, the density of the seeds is greater than that of the water, causing them to sink.
Use a magnet to collect all the iron. Then use water to dissolve all the salt. The poppy seeds will float and the sand will sink. Skim the top to get the poppy seeds, then remove the sand. Boil down the water to get the salt back.
Orange seeds will generally sink when placed in water due to their density. The high water content of the seed causes it to be denser than water, leading it to sink.
it will float as long as it is not fully covered water.
Arsenic is denser than water, so it will sink in pure water.
A fork will sink in water, as it is denser than water. The density of an object determines whether it will sink or float in water.
Asphalt is denser than water and will sink in water rather than float.
float
Float.
I have a marker which float in water.
i think it is ppeople because they float in salt water and sink in fresh water.
