Don’t do it – it won’t kill you, but it might make you blind. Food coloring may be able to do that if you eat it, but I would be wary of putting it into your blood in some other way. Also, putting something in your eyes is no more likely to get into your blood AND it might mess up your eyes.

3 as a food additive. It’s not exactly appetizing reading, I warn you—but basically, yes, it appears the chemical is safe to consume in small doses. (Blue 1 dye, used in at least one popular brand of green food coloring, is also on the list of suspects.)

If making in a half gallon jug of milk, you can use approximately 6-8 drops mint extract, 4 teaspoons vanilla extract, and about 10-14 drops green food coloring. Close the cap very tightly and shake to combine.

Detergent, such as liquid dish soap, is mostly surfactants. As the soap spread out from the cotton swab, it decreased the milk’s surface tension around it, and the higher surface tension surrounding this area pulled the milk (along with its food coloring) toward it.

When you first put the detergent on the milk, the negative end of the detergent molecules line up with the positive end of the water molecules. This causes the detergent molecules to zoom out in every direction over the surface of the milk and push the food coloring out toward the edge of the plate.

Here are some amazing things you can do with food coloring.

• Plant Experiments.
• Color Mixing.
• Sparkling Colors.
• Make Water Colors.
• Crayons.
• Frosted Mason Jars.
• Dye Flowers.
• Sugar Scrub.

When droplets of food coloring are placed onto the milk’s surface, the food coloring stays suspended on the surface in a small area. When you touch a cotton swab soaked in soap to the milk, the colors spread throughout the milk creating colorful swirls.

Answer: Soap is a surfactant. Therefore, when a drop of liquid dish soap is added to milk, the surface tension of the milk is reduced. As this occurs, the fat and protein particles in the milk can move more freely and easily.

Milk is made up of mostly water but it does contain vitamins, minerals, proteins and small droplets of fat. The soap and fat work hard to join together, which causes the movement. When food colouring is added we are able to witness this chemical reaction occurring.

The card stays on the upside-down jar because the pressure of the air molecules pushing up on the card is greater than the weight of the water pushing down. If you tip the jar at all, air will come into the jar and break the seal, causing the water to pour out. Tip the jar sideways and the water falls out of the jar.

Gently place the paper on the top of the glass. Move the glass over the container or sink. Gently place your hand on the paper, then flip the glass over. Remove your hand from the bottom and watch in amazement as the paper stays covering the glass and the water doesn’t spill out.

Make sure your cup is completely full, i.e. about to spill over the side. Gently place a dry card on top of the cup, making sure there is good contact over the cup rim. Carefully turn the cup upside down, keeping upward pressure on the card with your hand. When the cup is upside down, let go of the card.

Your body is used to feeling this kind of air pressure, so you don’t notice it. When you first turn the cup upside down, the pressure of the air inside the cup and the air pressure outside the cup are equal. All of this is possible because the water creates an airtight seal between the rim of the cup and the card.

When you turn the glass upside down, the water should stay in the glass. For this to work, make sure you’re stretching the hanky very tightly over the glass. I used a pillowcase, which is a little bit harder to hold onto.

The “trick” to this experiment is air pressure. In this experiment, you’re basically going to pour water in a glass, put a slip of paper over the glass, turn the glass upside down, and watch as air pressure keeps the paper in place—and the water “floating” in the glass.

Answer: If you put it in a clear glass you will see a bigger size of fork while if you put it out the fork will be normal in size because the molecules or lens will expand and created images that take the fork big as you look.

Essential Survival Knowledge: Gesture to Avoid (the Upside-Down Glass on Bar) In the United States and other countries, turning your glass upside-down might indicate that you do not want anything more to drink.

Some people tap their glass on the bar as a quiet tribute to absent friends and comrades. In Ireland, it was believed that liquor contained spirits that might be harmful if consumed, and tapping the glass dispelled those spirits. Some believe that you cheers to the future, but a tap on the bar acknowledges the past.

When someone taps their shot glass on the bar, it is to show respect to the bar or tavern that you are in as well as the employees of the establishment, especially the bartender. It is said that clinking glasses is to toast one another, but tapping the bar is to toast the house.

Toasting with an empty glass may be viewed by some as acceptable behavior for the non-drinker, though feigning to drink from such a glass would likely be seen as ridiculous. The person giving the toast should never do so with an empty glass, even if the glass contains nothing more than water.

Clinking glasses with water is looked down upon across many cultures. It’s believed that the act brings bad luck or even death upon the recipient, and in some cases, death upon yourself. The U.S. military actually forbids it with Naval folklore claiming that a toast with water will lead to death by drowning.

The Devil Sits on Your Loaf of Bread Beware of the devil lurking near your loaf of bread. It’s been said that if you don’t cut a cross into the top of the dough before baking it, the devil will sit on your loaf. Hence, one of the origin stories for Hot Cross Buns.

You take a sip after a toast is made in your honor Wrong! “Do not ever drink in your honor when there is a toast for you,” says Parker.

The proper etiquette is to say “health”, not “cheers”, but if the rest of your party is saying “cheers” then go with the flow and say it as well. A simple toast should mention the person or group being honoured, tying in something to do with the occasion or event.
