A hydraulic press is a device (see machine press) using a hydraulic cylinder to generate a compressive force. It uses the hydraulic equivalent of a mechanical lever, and was also known as a Bramah press after the inventor, Joseph Bramah, of England. He invented and was issued a patent on this press in 1795. As Bramah (who is also known for his development of the flush toilet) installed toilets, he studied the existing literature on the motion of fluids and put this knowledge into the development of the press.
The hydraulic press depends on Pascal's principle: the pressure throughout a closed system is constant. One part of the system is a piston acting as a pump, with a modest mechanical force acting on a small cross-sectional area; the other part is a piston with a larger area which generates a correspondingly large mechanical force. Only small-diameter tubing (which more easily resists pressure) is needed if the pump is separated from the press cylinder.
Pascal's law: Pressure on a confined fluid is transmitted undiminished and acts with equal force on equal areas and at 90 degrees to the container wall.

Crushed is the past participle form of "to crush".

A can opener (in North American English and Australian English) or tin opener (in British and Commonwealth English) is a device used to open tin cans (metal cans). Although preservation of food using tin cans had been practiced since at least 1772 in the Netherlands, the first can openers were not patented until 1855 in England and 1858 in the United States. These early openers were basically variations of a knife, though the 1855 design continues to be produced. The first can opener consisting of the now familiar sharp rotating cutting wheel was invented in 1870 but was considered too difficult to operate for the ordinary consumer. A breakthrough design came in 1925 when a second, serrated wheel was added to hold the cutting wheel on the ring of the can. This easy to use design has become one of the most popular can opener models.
Around the time of World War II, several can openers were developed for military use, such as the American P-38 and P-51. These featured a robust and simple design where a folding cutting blade and absence of a handle significantly reduced the opener size. Electric can openers were introduced in the late 1950s and met with success. The development of new can opener types continues with the recent addition of a side-cutting model.

It's a whole chicken! In a big tin! It's probably even worse than you think! Big thanks to the donator who paid a small fortune to have this sent over. (I feel I should have written "tin" in the title but the food's American so we'll go with can.)

If you want to try a cheeseburger in a can, good luck because they are only sold in Germany and are only shipped throughout Europe. For the record I am never eating cheeseburgers again.

In this video I put a soda can in the vacuum chamber to see if I can get it to explode. I talk a little bit about soda cans exploding and that you need to either increase the temperature of the can or reduce the pressure around the can. You can check out my science channel to see why shaking a can of soda doesn’t actually increase the pressure in an un-opened can of soda. I end up having to warm up the soda and then it finally explodes in the vacuum chamber. It leaves the soda completely flat with no carbonation left.

In this video I will show an interesting idea about making a rechargeable paint spray tool from a bottle. Now if you have old spray cans (from paint or artificial snow) lying around - you can give them another go! Just go over the steps in the video. Also if you charge it with water, you can water the plants, or make a soap base for when you're washing the windows. I’m sure you'll find a good use for it 🙂 Just find a suitable can. like parts from a can from artificial snow will not go well with paint, because it shoots in a straight line, ergo - for painting purposes use old spray paint cans!
