If you have heard about the website squidoo.com then you should check it out you can find lots of information about things you may not already know, its a great to learn stuff.
One someone posts something their page is then called a lens.
I found this cool lens, about the best ninja blender recipes, You will need a blender though don’t worry if you haven’t got a Ninja blender this is not necessary. The owner of the lense has created some great recipes. He has made things i didn’t even know you could create with a blender. I though blender was just for old people who couldn’t chew on food lol.
I suppose that may have been why they where initially created, but trust me you will be surprised at what you can make!
