This handy Snapchat trick lets you use extra filters

Snapchat is a great tool with some sneaky little tricks hidden away.

We've already shown you how to open a snap without the sender knowing, while everybody now knows their embarrassing pictures aren't so private once they're screenshotted. One of the most popular features of Snapchat is the array of filters available to users looking to spice up their photos. But did you know that you don't have to choose between your two favourite filters? If you want to double-filter your snap, simply scroll across to the first filter you'd like and keep your finger on the screen. Then, simply scroll across the screen with a different finger and you'll be able to combine any two filters you like.
