There is an embedding of the Mobius strip in $\mathbb{R}^3$, what is it?

Question

Let $M= S^1 \times ]0,1[$. Define the Mobius strip to be $N:= M/ \mathbb{Z}_2$ where the non trivial element of $\mathbb{Z}_2$ acts on $M$ by sending $(x,r) \in M$ to $(-x,-r) \in M$. I red that the manifold $N$ can be embedded in $\mathbb{R}^3$ what is this embedding? (I mean what is the function $f: N \rightarrow \mathbb{R}^3$ which is an embedding of $N$ in $\mathbb{R}^3$ ?)
