Add heat.
Melting is an exothermic process; we need heat for melting.
No, freezing changes a liquid to a solid. To change a solid to a liquid you need to apply heat. The change begins when the solid reaches its melting point.
We need test tubes.
Thermal (heat) energy must be added or removed in order to cause a change of state.
To make oobleck just a solid, you would need to add a material like cornstarch or starch in higher proportions to the liquid (water) until it forms a consistent, solid-like structure that no longer flows like a liquid.
To change the state of matter, you need to add or remove energy. For example, to change a solid to a liquid, heat is added to increase the temperature until it reaches the melting point. Likewise, to change a liquid to a gas, heat is added to increase the temperature until it reaches the boiling point.
