I make blending ingredients easier, and sometimes even hands free. It's also essentially what a dj is.

I go in dry and come out wet. The longer I'm in, the stronger I get. What am I?

A school’s paper companion, A scholar’s delight, An artist’s tool, And a banker’s nightmare.

I rock without a engine, sleep without a bed, I hang out between giants and cradle sleepy heads. I'm not a nest but sway in a breeze, Where daydreams nap and summer naps please. What am I?

I have been used for centuries, since the neolithic period. I have many uses, such as making an area fill with light when lit, acting as a lock for paper, and I also remove hair.
