In this interactive, When you change from solid to liquid, the particles tend to stay bunched close together in a roughly defined shape, rather than settling at the bottom of the container (see the image below).  This is deceptive for beginning students.  I use this interactive in the opening chapter of my book, to convey the idea that macroscopic properties are a function of atomic/molecular structure.  Because of the prominence of this interactive, this bug is very problematic.\r\n\r\n![image](https://user-images.githubusercontent.com/5090275/33576023-c6e00a18-d8fb-11e7-8d74-a0ca7269a26e.png)\r\n\r\n\r\nI would like to propose two simple solutions to this problem:\r\n\r\n1. In the initial solid state, position the atoms evenly across the bottom of the container, rather than a square shape.  While I understand the benefit of the square positioning for the solid (it conveys the idea of a definite shape), I think it's more important that that liquid not have a defined shape - and occupy the bottom of the container.\r\n2. Alternatively, create a new starting position for the atoms when you click from from solid to liquid.  As it is now, if you are in solid and click \"gas\", the image changes immediately from the solid phase to gas phase description.  This works well.  Doing the same thing with the liquid (everything settled in the bottom of the container) would convey this idea much more smoothly than is happening now.\r\n\r\nThank you for considering these changes.  Please let me know if you have questions or concerns - I'm happy to set up a call to discuss this further if it would be helpful.  I look forward to working with you in the years ahead as we incorporate these excellent simulations into our digital books.  "}}
