Change the sliders to change mass or volume arrow keys will change the object
JUST DO IT You can also use the arrow keys to control the slider, u just need to touch it first. When mass is greater than volume, It'll sink. but if the mass is lower than volume, It'll float. If the density of the object is above 1 (Greater than the density of the water), It'll sink while if the density is lower than 1 (The density of the water is greater than the object), It'll float.
