It didn’t take long for makers of flashing t-shirts to come up with one for the new Star Trek movie. Although you cannot beam up with it, it should probably scare any Klingons or fashionistas away. The battery pack is in the cotton shirt’s lining, is removable for washing and needs 4 AAA batteries (not included.) Choose from medium, large or extra large and live long and prosper in the officially licensed shirt that will cost you 29.95 GBP (~$46.00.)
