In this tutorial, we learn how to make one spoonful of cookie dough. First, clear off an area to work. You will need: butter, brown sugar, sugar, vanilla, flour, and water to this. First, place 1 spoonful of all the items into a mixing bowl and mix together until the dough reaches a nice consistency. This won't make you allergic since there are no eggs in it. You can add chocolate chips to this mixture if you want something different. Store the rest in the freezer if you aren't going to eat i...

How to make TCPO or bis(2,4,6-trichlorophenyl) oxalate, used in glow stick reactions. WARNING: This procedure should only be performed by, or under the direct supervision of, an experienced chemist. Please refer to the material safety data sheets of all chemicals for their hazards. Synthesis must be performed in a fumehood.
When caring for your pet, finding and treating their insect bites which may cause allergic reaction in your pets. Bites from wasps, spider, bees, and other insects may cause an intense allergic effect. First, check if your pet is still breathing and check if there is a stinger still is in their body and scrape it out using a credit card. Using a medication that contains only chlorpheniramine if your pet is conscious, breathing, and not vomiting. Using this method, you will be able to ensure t...
Do you play an intensive sport, like soccer or football, that requires you to be able to not only run quickly towards a target area far away, but also to be able to catch a flying ball with precision that far away? Then you'll benefit from the speed and quickness training methods presented in this video.

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...

Instead of responding to a WhatsApp message with short texts like "LOL" or thinking too hard about something meaningful to say, use an emoji reaction. They cut down on clutter in group chats and take up less space than typing emoji individually in a conversation. WhatsApp initially limited reactions to just six emoji, but a new update lets you use any emoji you want.
Apple hasn't really changed notification sounds on the iPhone since iOS 7. So how come you hear strange pings, plunks, and doots coming from your iOS device? No, it's not an app you downloaded (although third-party apps can have their own notification sounds). Instead, what you're experiencing is likely the result of updating your iPhone to iOS 13.
Wherever there are people, the party is sure to follow. Well, a party of microbes, at least. That is what scientists at NASA's Jet Propulsion Laboratory have found after a 30-day microbial observation of the inflatable lunar/Mars analog habitat (IMAH).
Poison ivy, poison oak, and the lesser known skin irritator, poison sumac, can all cause a conundrum in the search of itch relief: to scratch or not to scratch. Fortunately, there are a number of home remedies one can try to help alleviate the itch(ing), with many like coffee, a banana, baking soda, or mouthwash likely already in-house for most.

In this tutorial we learn how to take an acid and base to make salt. To start, you will first need to take an acid of your choice, this can be something like vinegar. After this, you will combine the acid with a base and then wait for it to react. Once it starts to react, gases will release from them and you will end up with some salt! Be sure to put a cap on the container while the reaction is happening. This will allow the reactions to come together and the gases to react. Have fun and do t...
In this video, we learn how to balance an easy chemical equation. You can do your equation by testing it out with the actual chemicals. Watch and see what the reaction is as they start to mix together. To balance this reaction out, you will need to analyze the number of atoms that each element has on both sides of the equation. For it to be balanced, you must have the same number of products and reactants in the equation. You cannot create or destroy matter, you can only change its form, so r...
