Tools and materials,

A pile of popsicles

Rope (optional)

A pair of reliable hands

1, first put two popsicles into an X shape as shown in the figure. Give an x-shaped popsicle. The top is 1 and the bottom is 2.

2. Then add another popsicle stick to one side of the X-shape, and place the newly inserted stick 3 at the position shown in the figure, above the stick 1 and below the stick 2, and flatten it.

Add another rod 4 and insert it below rod 2 and above rod 3.

3. Repeat the above steps patiently.

Continue to add new popsicles like this until you get bored. Of course, if you are patient, the cobra will be longer, the explosion will be brighter and it will be more difficult to clean up.

4. Trigger

In the production process, apart from releasing the hand to detonate the cobra, there is another detonation method, that is, an popsicle stick is inserted under the stick 1 and the stick 3 to press the stick 4. If you add a rope to this popsicle, you can also detonate the cobra from a distance. Here, this popsicle is called a trigger.

5. detonate

After hard work, I finally got the cobra popsicle. Pull the trigger hard, and the cobra will raise its head and spray itself into a room full of popsicles. This is the best gift for my roommate.

There are even more amazing ice cream sticks here.

Precautions:

1, the domino gap should be reasonable, neither too big nor too small.

2. Leave a space for one or two dominoes between more than a dozen dominoes to avoid touching them.

3. When using dominoes to form some characters and patterns, we should not only consider how to display the strokes of characters, but also how to set dominoes at the junction of pattern lines.
