Two solids that go straight to gases (a process called sublimation) are:

1. Dry ice (solid carbon dioxide): This is a very common example. Dry ice sublimates at room temperature and atmospheric pressure, creating a visible cloud of carbon dioxide gas.

2. Iodine: Solid iodine crystals will slowly sublimate at room temperature, releasing a purple vapor.
