The Battle of the Barrels is a transportation illusion also known as Barricaded Barrels, Through the Eye of the Needle or the Black and White Barrels. The illusion consists of two topless/bottomless barrels openly displayed on castered open framework supports. A female assistant then climbs inside a barrel and wooden bulls-eye targets are affixed to either end of the barrel. The second barrel is shown empty, sealed on one end and with four solid metal bars fixed across the other end.
