How is a cannon made?
Cannon were cast in molds of clay, suspended vertically in a pit. Normally, they were cast breech down; this placed the molten metal at the breech under pressure, resulting in a denser and stronger alloy around the chamber, the most critical point. These were cast into the bronze and remained a part of the gun.
What will happen if the rubber band is released?
You input potential (stored) energy into the rubber band system when you stretched the rubber band back. Because it is an elastic system, this kind of potential energy is specifically called elastic potential energy. When the rubber band is released, the potential energy is quickly converted to kinetic (motion) energy.
Why do rubber bands make different sounds?
The longer length of the rubber band makes a low, long, heavy sound and vibrates at a slower rate of frequency. The shorter length of rubber band makes a high, short sound and vibrates at a faster rate or frequency. The shorter length causes the band to vibrate faster and produces a higher pitch.
How do you TP a house?
Throwing Technique. First: Hold the roll with your dominate throwing hand. Second: Place your first three fingers (pointer, middle, and ring fingers) on the back of the roll. Third: Pinch the roll firmly with your pinky and thumb. Fourth: Drape the rooster tail over the roll down the back of your hand and arm.
What leaves are good for toilet paper?
The best leaves to use instead of toilet paper! Magnolia Leaves. Big Leaf Maple Leaves (Acer Macrophyllum) Hazel Leaves (Corylus) Red Mulberry (aka Morus Rubra) Wooly Lamb’s Ear Leaves (Stachys Byzantina) Dock Leaves (Rumex Obtusifolius).
Are cannons legal to own?
Under the federal National Firearms Act of 1934, large-bore cannons are classified as “destructive devices.” To obtain one, pre-approval from the federal Bureau of Alcohol Tobacco Firearms and Explosives is necessary. A $200 tax stamp is required to possess one.
How was the first cannon made?
Fire lance The cannon may have possibly appeared in China as early as the 12th century, but did not see wider use in the region until the 13th century. The cannon was likely a parallel development or evolution of the fire-lance, a 12th-century gunpowder weapon that combined a tube of gunpowder with a polearm weapon.
What metal were cannons made of?
Most cannons were made of cast iron and that is the kind most often found by divers. The material used to make the other type is variously known as bronze, brass or copper alloy, although the material used to make them is not a true bronze but is some alloy of copper.
How do you make a marshmallow catapult?
Instructions Using 3 marshmallows and 3 skewers, form a triangle. Use 3 more skewers and 1 more marshmallow to form a pyramid. Loop thin rubber band over topmost marshmallow. Tape plastic spoon securely onto the end of another skewer.
How do you make a stick slingshot?
Step #1: Make the slingshot. Make elastic bands. To begin, tie 2 rubber bands together to make a long band. Repeat. Make a pocket. Cut a small rectangle out of a scrap of leather or sturdy cloth. Assemble. Tie the rubber bands to the ends of a forked stick.
What does J mean in kinetic energy?
The joule (J) is the SI unit of energy and is named after English physicist James Prescott Joule (1818–1889). If we go back to the equation for kinetic energy written above, we can put units in (kg for mass and m2s2 m 2 s 2 for velocity squared).
What happens if you just let the bob swing back and forth what happened to the energy?
When you let go of the raised bob, its potential energy is converted to kinetic energy as it swings down with increasing speed, and then back to potential energy as it swings up on the other side with decreasing speed.
Why does a rubber band become a lighter color when stretched?
Colour can come from pigment particles embedded in the translucent rubber matrix absorbing light. When you pull the band the particles become separated by a longer distance, but being themselves inelastic remain the same size. Hence the amount of absorption per unit area decreases, and the band become lighter in color.
What if we could hear the sun?
If space were replaced with air and we could hear the Sun, it would be incredibly noisy – the output of the Sun is equivalent to 10 million keys, or notes, of a piano. Sound intensity decreases with distance, which means that the Sun would deliver a much smaller 125 decibels to the surface of our planet.
Are there changes in the note when you plucked?
There are changes when we pluck the stretched band. Explanation: There are normally two states for a band. One is Normal state, where there is no external tensile force applied on it.
When you tighten a guitar string What happens to the pitch?
Tension refers to how tightly the string is stretched. Tightening the string gives it a higher frequency while loosening it lowers the frequency. When string players tighten or loosen their strings, they are altering the pitches to make them in tune.
How does the toilet paper gun work?

How do you clean up tp?
Step-by-Step Guide to Getting Toilet Paper Out of Trees Act before the rain. Grab a trash bag and start from the top down. To safely remove TP from tall trees, use a rake or lengthy yard tool. If you can’t reach the TP, try a leaf blower. If the TP on the tree is near a power line, don’t risk it.
