Much like in sword swallowing, this can take a lot of practice. The sneeze reflex is one of your body's defense mechanisms against bacteria and viruses-- when you sneeze, you forcibly expel particles that could make you sick.

The Amendment Process. There are essentially two ways spelled out in the Constitution for how to propose an amendment. One has never been used. The first method is for a bill to pass both houses of the legislature, by a two-thirds majority in each. Once the bill has passed both houses, it goes on to the states. This is the route taken by all current amendments.
However an amendment is proposed, the final step is ratification. Two methods for ratification are provided - by three-fourths of the state legislatures or by three-fourths of the states in convention. This topic concerns the latter of these two. Ratification Conventions. The normal course of events, when an amendment to the Constitution has been desired by the people, is for Congress to pass the amendment and for the state legislatures to then ratify. Congressional proposal of the amendment is by a two-thirds majority vote in both houses.
