Luminol x Hydrogen Peroxide = Science [Gif via Reddit]

This bizarre-looking creature, which lurks off the coast of Chile and Peru, is part of a family of sea-dwelling marine invertebrates known as sea squirts. Despite the fact that they resemble rocks so much that they are nearly indistinguishable when surrounded by them, they contain a mass of organs surrounded by layers of blood, skin, and muscle, and will bleed when sliced or cut in half, just like any other animal. Referred to as ‘Piure’ in Spanish, they are considered a delicacy in South American countries, even though locals describe them as having a flavor that is bitter, soapy, and iodine-like. 

Mysteriously, sea squirts contains nearly ten million times the normal concentration of the rare element vanadium in their blood, and nobody knows why. It is thought to be used as a chemical deterrent against predation, but this is currently an unproven theory.

DIY 1 Ingredient Rock Candy Tutorial from Growing a Jeweled Rose. When listing ingredients I do not count water as an ingredient. This is such a fun experiment for kids and if it doesn’t work you are out the cost of sugar.

Materials: 1. A D size battery 2. Paper clips 3. 3 feet of thin coated copper wire 4. A 3 inch large iron nail

Steps: 1. First, leave 8 inches of wire at one end and wrap most of the rest of the wire on the nail ( do not overlap the wires). 2. Next, leave 8 inches of wire at the other end of the nail. 3. Then, remove an inch of the plastic coating from both ends of the wire and attach one end of the wire to one end of the battery and the other wire to the other end of the battery. 4. Finally, put the nail near the paper clips and it should pick them up!

Lesson: Magnets that cannot be turned off like ones on our refrigerators are called permanent magnets. Since the magnet we made can be turned off and on, it is known as an electromagnet. They run on electricity and are only magnetic when the electricity is flowing through the wires, which has the molecules in the nail attract to the metal paper clips.

Materials: 1.4 soda cans 2.2 ceramic magnets 3.ruler 4. Five hex nuts 5.an empty tall drinking glass 6.adult Steps: 1.First, put two soda cans on each side at the ruler length apart. 2.next, stack the other two soda cans with one on each can. 3.then, put the ruler on top of the soda can towers and put The drinking glass between the towers. 4.next, place one magnet on the ruler and put the other magnet underneath the ruler so the magnets attached to each other. 5.then, attach the hex nuts with one of the time to the magnet underneath the ruler 6.finally, slowly detach the hex nut chain and bounce it on the edge of the glass. (Make sure the edge is directly below the magnet) Lesson: The magnets are causing the hex nuts to attract each other, and, thus, the hex nuts create their own magnetic field. When you detach the hex nuts from the magnet, there magnetic field is weaker.
