Abracadabra! It's gone!
Question: Can you make an object almost
invisible?
Hypothesis: We think that you can make an object almost invisible by using two objects with low reflection and roughly the same refraction rate.
Procedure:
Special Needs: Water. |

The Science behind it
We see objects because of reflection and refraction. Some objects have low reflection, such as glass, which makes them hard to see. As light passes through an object, like glass, the speed at which the light travels will change. This causes the light to bend. This is called refraction. We are able to see objects because of refraction or bending of the light. Some objects will bend the light more than others. The degree to which the light is bent is the refraction rate. If light passes through two different objects with the same refraction rate, the light will not bend, and you won't be able to see it.

Conclusions
In conclusion, we accept our hypothesis because the test tube filled with baby oil disappears due to the refraction rate, which is the speed light goes through an item. If an item and the item surrounding it have about the same refraction rate, the inner item appears INVISIBLE.
