Introduction: How to Make a Simple Flapping Pterodactyl Toy
In this Instructable I'll show you how to make a simple, but quite pleasing toy.
It's a pteradactyl which flaps its wings as you move a straw up and down - this is based off something I saw at the Centre for Life in Newcastle, UK. A fine institution.
Things you will need:
Some paper
Something to colour your Pterodactyl in with
Some tape
A scissors
2 straws - they have to be of different widths so that one can fit inside the other

Step 1: The Pterodactyl
Find a nice picture of a pterodactyl, and colour it in to your own tastes
Step 2: Make a Hole in Your Pterodactyl
Cut a hole in the middle of your Pterodactyl by bending it slightly and using a scissors
Step 3: Preparing the Skinny Straw
Take the smaller of your two straws and split it down the centre using your scissors. This split only needs to be about a centimeter long
Step 4: Sticking the Skinny Straw to Your Pterodactyl
Put the skinny straw (which you've just cut) through the hole in your Pterodactyl.
Bend the cut sides of the skinny straw back and tape them to your dino.

Step 5: Preparing the Bigger Straw
Cut the bigger straw down so that it's smaller in length than the skinny straw (about three-quarters the length of the skinny straw would be fine). In my case that meant cutting the big straw about an inch below the bendy part of the straw. It might be different for you, obviously enough.
Then split your big straw, using your scissors, until about half way down. Then bend the now split sides of the straw back, like in the photo

Step 6: Combining the Straws
Slide your big straw down the skinny straw as far as it will go, making sure that the split end is towards the Pterodactyl
Step 7: Attaching the Wings
Finally, just put a small piece of tape connecting the ends of the straw to each wing
Step 8: Enjoying Your Pterodactyl
As you slide the big straw up and down, your Pterodactyl will flap its wings!
Simple, and endlessly amusing.
