answer to brain teaser #3, solving logic-grid brain teasers

Answer to free brain teaser #3

First, the waiter stuck the match into the lemon wedge, so that it would stand straight. Then he lit the match, and put it in the middle of the plate with the lemon. Then, he placed the glass upside-down over the match. As the flame used up the oxygen in the glass, it created a small vacuum, which sucked in the water through the space between the glass and the plate. Thus, the waiter got the water into the glass without touching or moving the plate.
You can try this experiment at home with appropriate supervision.

Solving logic grid brain teasers

How do I know I have gotten a brain teaserShow Answer that requires me to draw a logic grid?

Brain teasers that require you to draw a brain teaser have two or more things you have to put together. It’s usually a person, with a last name, a time or place, and an object or thing connected to the person. They will usually give more than one cryptic clue related to the topic at hand. This week’s free brain teaser is a logic grid one, so draw up a logic grid to solve it.

Free brain teaser #4

Since Jeremy and his friends now had more apples than they could possibly eat, they needed to find ways to use them up. So each friend hit the cookbooks and started busily baking (it's remarkable how many yummy recipes there are for apples!). As it happens, each friend did such a good job making one recipe, that it was forever after their specialty. Fortunately for them, each one had a different specialty. Determine the name of each friend's special recipe, the type of apples and special ingredient each dish used, and the number of apples each recipe used.

1. The recipes, in no particular order, were the recipe using cinnamon, the recipe using three apples, the apple tarts, the recipe using Macoun apples, and the apple crisp.

2. The recipe using the Cortland apples used one apple more than the apple bread but one apple less than the recipe using the raisins.

3. The muffins used one more apple than the recipe with the walnuts but two less apples than the recipe using the Red Delicious apples.

4. The nutmeg was used in the apple crisp, which used more than two apples but less than the apple pie used. The apple pie used more apples than the treat with the raisins.

5. The apple muffins, which weren't made with Macoun apples, used pecans.

6. The Empire apples weren't used in the apple crisp. The recipe using the McIntosh apples used the most apples.

Science based brain teaser, Brain teaser #4

Science based brain teasers – what do I need to know?

Science based brain teasers are just that. They are based on science. As a result, a good understanding of physical and biological world and the associated laws are going to be very useful. If you have a good understanding by observing a lot of things, then that is useful too.

Brain teasers based on science are therefore not that hard to solve if you have a good grounding in science.

Here is this week’s free brain teaser:

Free brain teaser #3

A man in a restaurant asked a waiter for a juice glass, a dinner plate, water, a match, and a lemon wedge. The man poured enough water onto the plate to cover it.
"If you can get the water on the plate into this glass without touching or moving this plate, I will give you $100," the man said. "You can use the match and lemon to do this."
A few minutes later, the waiter walked away with $100 in his pocket. How did the waiter get the water into the glass?

Hint

The glass will be upside down when the water is in it.

answer to free brain teaser #1, about optical illusions

answer to free brain teaser #1

paradox

optical illusions – a form of brain teaser

optical illusions rely on the eye to make the impossible look possible, or to fool the mind. There are many optical illusions that exist. The most common one is with lines that look of different length. That is commonly known as the Mueller-Lyer illusion.

Optical illusions that tease the mind have been around for a long time. The most common ones, however, are ones by an artist called M.C Escher. These are known sometimes as Esher’s, sometimes as ‘impossible structures’, and sometimes by other names. Esher’s works contained elements of mathematics. Although he was not a mathematician, he was interested in mathematics and frequently incorporated maths into his artworks. Most of his most famous artworks are optical illusions, and may or may not be coloured. Escher worked with many print mediums, and some of his paintings are in watercolour, some in woodblocks, while other still are in other forms of printing.

Here is this week’s free optical illusion for you to enjoy:

Brain teasers for free

Each week, I will be providing a free brain teaser for you to solve or look at. These will challenge your mind to look at them in different ways. I will also provide hints and clues as to how to solve if necessary. Each week, beginning next week, I will provide the solution to brain teaser from the week before.

Why do brain teasers?

Brain teasers are a way to relax. You can sit down with friends or family to discuss various ‘answers’ and provide a point of conversation when the answer is discussed and revealed (if no-one can get them, that is).

Brain teasers also keep your mind active and stimulated. An active mind helps to fight Alzheimer’s disease in the elderly. As we know, Alzheimer’s disease is a problem in the elderly. You can help combat this by doing brain teasers and other mind stimulating activities. Don’t forget to keep fit in other ways also.
