Either attach something heavy to the ice, or play with the density of the water, or of the ice (adding something to it).
anything denser than the water will sink in it.
You can make a feather sink in water by compressing it tightly into a smaller, denser shape. This reduces the amount of air trapped within the feather, making it heavier and therefore able to sink in water.
An egg will sink in water but will float in salt water. An egg will sink faster in hot water than it will in cold water.
To make fruit sink in water, you can remove any air bubbles trapped within the fruit by gently squeezing it or piercing it with a fork. This will help reduce its buoyancy and allow it to sink. Alternatively, you can weigh the fruit down with a heavy object or place it in a container filled with a denser liquid, such as a salt solution.
Weigh the item down or find a way to fill it with water. For it to sink it must have a greater mass than the liquid it is placed in.
Objects sink or float depending on their Mass and density. If the object has a Density LOWER than water, it will float. Higher than water will sink. You can find density by multiplying its Mass times its Volume, there you have its density. Water has a Density of 1, things with lower may sink, only slightly if there isn't much difference.
Pour the water out
Paper will sink once it has absorbed enough water to make it heavy.
put water in it
Yes, it may make oil sink if at some temperature the density of water goes lesser than that of oil.
Tap water sink water well water ect....
no
