Making a cannon for a school project is a great way to demonstrate knowledge of physics and engineering. To make the cannon, you will need a few basic materials such as a cardboard tube, a cap for the tube, construction paper, tape, and a few pieces of scrap wood. First, you need to cut a piece of the cardboard tube to the desired size of your cannon. Then, cut a piece of construction paper to fit around the tube and tape it in place. Next, cut two pieces of scrap wood to the same size and attach them to the tube using tape. Finally, attach the cap to the end of the tube using tape. Once the cannon is complete, you can fill it with a small amount of sand or small stones, and use a rubber band to shoot it. With some creativity and research, you can make a unique and fun cannon for your school project. Can You Own A Cannon In Usa Heath, Byron (2005). Discovering the Great South Land.

While there is evidence of cannons in Iran as early as 1405 they were not widespread. [73] This changed following the increased use of firearms by Shah Ismail I, and the Iranian army used 500 cannons by the 1620s, probably captured from the Ottomans or acquired by allies in Europe. [74] By 1443, Iranians were also making some of their own cannon, as Mir Khawand wrote of a 1200kg metal piece being made by an Iranian rikhtegar which was most likely a cannon. [75] Due to the difficulties of transporting cannon in mountainous terrain, their use was less common compared to their use in Europe. [74] Eastern Europe When a cannon had to be abandoned such as in a retreat or surrender, the touch hole of the cannon would be plugged flush with an iron spike, disabling the cannon (at least until metal boring tools could be used to remove the plug). This was called "spiking".

I made my second batch of gender reveal powder differently (and pink!), with the desire to get it completely done as fast as possible. And it totally worked with ZERO mold in the powder over a week later, so feel free to use this new method instead! It still doesn’t guarantee your powder will never mold, but if you’re in a rush because you’re going to use the powder soon anyway, it is absolutely perfect!Hodgkin, John (1902). Rarioria.
