Paintball gun
From Tardis Wiki, the free Doctor Who reference
The paintball gun is a handheld weapon created on Earth that fires small paintballs as projectiles. Wilf used the weapon to attempt to blind a Dalek by shooting it in the eye stalk. However, the device was useless when the Dalek vaporised the paint, clearing his vision again. But it was destroyed by Rose with a better gun prompting Wilf to ask to swap weapons (DW: The Stolen Earth)
