This is a common question, and the answer is actually quite simple. You only need a cutter and a cutting board. To juice, an orange without a juicer first cut off both ends of the orange. Then, stand the orange up on its end and slice it in half from top to bottom.  Finally, cut each half of the orange into thin slices and juice them. If you want to make a smoothie instead of juice, just blend the orange slices with some other fruits or vegetables. This is a great way to get extra vitamins and minerals in your diet. So, don't worry, next time you have an orange and don't have a juicer! You can still enjoy fresh orange juice without a machine.
