Thanks to a post by our friend Lisa, she introduced us to the world of ‘stick bombs‘. Think dominoes but with Popsicle, ahem, craft sticks. Weaving them together to store up the energy under tension, you drop them, or in this case unleash them and away they go. We did up a video showing it off and you probably just want to watch that, and only read on if you are ready to build your own.
We had to acquire some wide, or jumbo, sticks as the smaller ones we had were just too stiff of a spring to do the ‘cobra weave’ style of stick bomb run. Why is it called a cobra weave? I’m guessing because it looks like a massive cobra snake is raising up out of the floor and spitting venom at you in the form of sticks. It really is a sight to see.
If you’re going to try it yourself, get about 200 of the sticks (we had 225, but imagined using a box of 500, alas the local shop just had packs of 75) and give yourself an hour or two to get setup. The hardest part is getting it started as all it wants to do it jump up at that point, and you need a bit of distance to get it settled. We started with this instructable we found, but with the challenge of getting it started, and I was a little unsure it was loaded the right way (their video didn’t have a great cobra shape) I checked around and found a how to make a mini-cobra weave (who knew there is a more complex cobra weave too) by the domino dude which had you build some of the weave first, and then lock it off, instead of starting with the lock like the instructable did. The kids were also anxious to see if it worked so after 50 sticks or so we set it off, and started again. Warning, you might want to wear gloves of some sort as I found the wood really dehydrated the skin of my finger tips and if you’re really geeky protective eye wear. There are smaller handheld weaves the kids can do too, this is what happened here as the repetition of building the long chain didn’t hold their interest the whole time.
Here are some photos of our progress as we went. In the video he gives some special way to make a turn… I just grabbed it and twisted it a bit as needed, didn’t feel I needed to do anything special with the laying of the pattern. Also, see how we added a bit of weight to the start of it, the lock was a tad slippy at first so I just stuck that on to keep it all in place until we were ready.
Oh, and some people will think it makes an incredible mess to clean up — it doesn’t. The kids had the sticks put away in all of 3 minutes. Have fun making your own.
