What was created to get around the prohibition law?

If you mean how did Prohibition" end, well as it became constitutional law by ratification of the 18th Amendment to the US Constitution, in 1933 the federal government enacted legislation that made "3.2%" beer legal and later in the same year the 21st Amendment was ratified that repealed the 18th Amendment. If you mean how did people get around prohibition, people made alcoholic beverages illegally, at home, an entire illegal trade grew up and became extremely powerful and created huge problems, and illegal bars opened and the name "speakeasy" became applied to them.
