Woman Disputes TSA Portrayal of Her Cupcake A Massachusetts woman says federal safety officials are mischaracterizing a frosted cupcake in a jar that was confiscated from her at a Las Vegas airport. The Transportation Security Administration says it considered the icing on the cupcake a gel exceeding the 3-ounce limit for airline carry-on luggage. The limit is designed to stop terrorists seeking to evade detection by using explosives made of plastics, liquids or gels. The TSA says in a blog post the cupcake taken last month had a thick layer of icing inside the jar. But Peabody (PEE'-buh-dee) resident Rebecca Hains said Wednesday her jar consisted of three layers of cupcake, each topped with a medium layer of icing, not a thick layer. The bakery that makes the red velvet cupcake has renamed it National (Security) Velvet.
