In this tutorial, we learn how to make your own nylon. You will need: pipettes, pipette filler, forceps, beaker, stir rod, sebacoyl chloride and hexanediame solution. Now, pour some of the hexanediame solution into the small beaker. Add in a food coloring if you want to make this a specific color. After this, add in 4 cc's of sebacoyl chloride and carefully drip into the side of the beaker. You should see a layer of where the two liquids are after this. Now, take your tweezers and reach into ...
Bottled-beer chuggers the world over already know that letting air into your beverage with a straw makes it pour faster into your mouth. Did you know, however, that the same technique can be modified and used to empty a fluid into another container (or onto the floor) even more quickly? This video will show you how to use a modified straw technique to introduce air into a large bottle of water or other drink bottle, causing the contents to empty at a torrid pace.
Learn how to make liquid sculptures from a hand warmer in simple steps. First buy an instant reusable hand warmer which has sodium acetate in it and keep it ready.

In this tutorial, we learn how to make hydrochloric acid from salt. First, you will pour some salt into a distil flask. After this, you will add in some concentrated sulfuric acid to the salt. Next, you will let these react with each other. You will start to see gasses bubble up and the excess hydrogen chloride gas come out through the top of the tube. To create a stronger reaction, you can add heat underneath the reaction. Then, test this by exposing it to ammonium chloride. If it's the righ...
Have you ever seen water freeze instantly? This "Quick Clip" shows some of my personal experiences with making instant ice using a bottle of water supercooled in a freezer.
A Peltier module allows you to turn heat into electricity. Because you can place it in areas that are normally warm anyway, the electricity created is "free" in a sense, though it does work best when one side of the module is cold and the other is hot. In other words, all you'll need for this project is the Peltier module and a cooler surface such as soil or water, and a warm area such as a well lit window or warm pan.
In our personal experience, the hardest part about a science investigatory project is simply coming up with a good idea. And we suggest that for your investigatory project you find a topic that's both novel and useful.

310tutoring shows viewers how to easily convert Grams to Moles for Chemistry. If you have 120 grams NaOH and we want this in moles we need a periodic table. Now, you need to figure out what the mass is of each individual element in NaOH. You need the mass of Na, O and H. Na mass is 23, O has 16 and H is 1. Add all of these up to get the molar mass of NaOH is 40 g/mol. Now use this to convert 120 g to moles. Now take 120 grams NaOh and multiply this by 1 mol NaOH/ 40 grams NaOH. You can cancel...
