This is a neat, and very quick little toy that I first came across on the "Happy Scientist" website.
A couple of minute's work, and you have a toy to keep the kids happy, a fun craft activity, a hook for a fascinating science lesson, and probably the cheapest and quickest at that.
Step 1: Materials and tools
I have successfully used lollipop sticks, tongue depressors, coffee stirrers and chip forks.
I guess it doesn't have to be wood, but it does need to be fairly rigid.
Step 2: What to do
For your own comfort, carve, scrape or sand the narrow part to a more rounded cross-section. Corners and sharp edges will cut your thumbs or increase the chance of blisters.
You don't have to stick with the plain, er, stick. You can carve and shape to your heart's content.
The basic carving takes only a couple of minutes with a decent sharp knife. I haven't tried, but if you add a sanding bit to your rotary tool, you could probably churn them out in seconds.
Step 3: Safety
OK, I don't really have to warn you about safe use of blades, do I?
But, when you throw a poong stick, it can fly off in unpredictable directions, and it has a narrow, pointy end.
If there are several people using poong sticks at once, you should seriously consider issuing eye protection, especially if you are doing this as a group activity with children.
