Cardi B threw a microphone into a crowd during a concert at Drai's Beachclub near a Las Vegas casino on July 29th. This microphone has now become a part of pop culture history and is available for purchase on eBay. As of Wednesday morning, the microphone has received 76 bids and is selling for $90,900. The proceeds from the sale will be donated to two charities - the Wounded Warrior Project, which supports veterans who have been injured, and a local Vegas charity called Friendship Circle Las Vegas, which benefits teenagers and young adults with special needs.
