Hallo! This is an origami bat that flies fairly well. Enjoy!
Step 1: Folding
Follow the pictures in order:
1. Start with a water bomb base.
2. Fold up the flaps.
3. Rabbit ear fold the flaps as shown.
4. Turn over.
5. Fold the top half down, bringing the ears up with it.
6. Reverse fold the ears and add wing tips.
Your done! To fly, hold horizontally and flick forward. I have caught thermals with this in my front yard on a hot, windless day, so watch out!
