Glass Harmonica

What is Glass Harmonica?
It is a musical instrument invented by Benjamin Franklin in 1761. That was the time of colonial Era, and Benjamin used to travel to Europe often. During those travels, he attended many concerts and was excited to see how artists and musicians had been using musical instruments made up of glass.

He decided to build one of his own and succeded in 1761 when he completed his Glass Harmonica. Where he carefully designed the glass bowl to produce a different sound when touched by a Moistured finger.

These bowls were connected with each other using the rod in the center and do not touch each other.

When it loses its popularity?
This invention by Benjamin Franklin got very popular till the start of the 18th century but by the end of 1820, its popularity got faded away.

How can I use it for my science project?
But for students, who want to do something very exciting with musical instruments, you can build one for your science project with all the seven nodes. And during the presentation, you can play a beautiful song to impress everyone present.

The Potential for Vegetable-Oil-Based Fuels as a Substitute for Diesel

What is vegetable oil fuel?
The oil produced from Vegetable can also be used as a fuel with some modifications in the engine, to power diesel engines we use for our cars. Also, the mixture of this fuel with diesel has got very popular recently and called Bio Fuel.

Fire Ants: Height to Nutrition

Determine the maximum height at which fire ants would come to get food. Set out different types of food and then measured the height that the fire ants came to get that food.

Imported Fire Ant Control Using Household Products

You can use several types of household products to determine which ones controlled fire ants the best. You can use products such as Epsom salt, PeptoBismol®, and oranges. You need to make a transect to determine the initial numbers of fire ants in a mound, then present the household product to the mound. Finally, count the remaining fire ants after exposure to the household product.

Glass Harmonica by Ben Franklin

The science behind it has to do with frequency and vibrations. You could make your own glass harmonica of sorts by pouring water into a set of glasses. Align them to make a row. Fill each of them with different amounts of water (fill each with a little more water ). And then use a spoon and tap each of them in order. They should make a Do Rei Mi sound.

How to build rocket?

Air rockets are those which use the power of compressed air (pumped using a bicycle pump) for their launching. They are different from conventional rockets which get a supply of thrust force in large part of its flight, instead, the thrust of an air rocket is completely expended in the first instance of flight. They use an initial push from compressed air all in once and can fly about 200 to 300 feet. They are simple to build.

Newton laws as they applied to rockets
Rocket is a missile that obtains from a thrust engine. It is based on Newton's third law of motion which states that every action has an equal and opposite reaction. This thrust can be achieved in various ways but one of the most common techniques is compressed air. We have already discussed it in our Air Rocket Post.
