Pythagorean cup. Cross section Cross section of a Pythagorean cup. A Pythagorean cup (also known as a Pythagoras cup, a Greedy Cup or a Tantalus cup) is a form of drinking cup that forces its user to imbibe only in moderation. Credited to Pythagoras of Samos, it allows the user to fill the cup with wine up to a certain level. If he fills the cup only to that level, the imbiber may enjoy a drink in peace. Form and function[edit] A Pythagorean cup looks like a normal drinking cup, except that the bowl has a central column in it – giving it a shape like a Bundt pan in the center of the cup.
When the cup is filled, liquid rises through the second pipe up to the chamber at the top of the central column, following Pascal's principle of communicating vessels. Common occurrences[edit] A Pythagorean cup sold in Crete A Pythagorean cup sold in Samos Hero of Alexandria (c. 10–70 AD) used Pythagorean cups as hydraulic components in his robotic systems.

The Devil’s Pet Candle. Thorunn Arnadottir is a London-based designer originally from Iceland. Her latest project, The Devil’s Pet, is an innocent geometric kitten candle that once lit reveals a ghostly metal skeleton. The ball of yarn is the candle wick itself, so it will end up as a devilish looking scorned cat skeleton with the ball of yarn on fire on its side. [...]
The candle brings to light (literally) the contrasting and rich typologies attached to an every day object such as a candle and how we seem to have lost sight of it’s original function and meaning.

Humans create clouds of fog the same way clouds in the sky form. Ad Steps Method 1 of 3: Make fog in a bottle with hot water In this case the condensation is caused by the temperature variation between simple ice and hot water. 1Fill up the jar or bottle completely with very hot water and let it stay there for about 65 seconds. 4Place ice cubes in the bag or strainer water vapor from the bottom of the bottle contacts the cold air created by the ice cubes and begins condensation.
Method 2 of 3: Make fog in a bottle with alcohol Making fog in a bottle with alcohol is the same basic technique of making it with hot and cold water and air. 1Fill a suitable container 1/3 full with hot water. 2Add a few drops of alcohol.

Marc Johns: Drawings on paper towels. I did these two below in a Starbucks washroom: New to the site? Look at some more nonsense drawings here. I originally posted these paper towel drawings about 2 years ago to Flickr and Vox, long before I had this site. They have since turned up on a number of blogs (and now tweeted by Ashton Kutcher and Rainn Wilson, and blogged by Urban Outfitters and Alltop), so I thought I'd get in on my own action and post them here. Oh, and one of these photos appears in Rainn Wilson's book Soul Pancake. Glue Prints!!! Spin Art Without The Spinner Creations. Last week I did a posting of Spin Art Without The Spinner and we ended up with some really lovely circular paintings as you can see below! Be sure to check out my post about making Spin Art Without The Spinner here. We didn't make the paintings into anything in the Spin Art Post, but I questioned my readers what could I do with them? There were some fabulous ideas!
Some of the suggestions were flowers, butterflies, a bunting, animals, and a mobile! All such inspirational ideas!!!! You will see that we used some of the suggestions! Thank you everyone for your Wonderful ideas! We started with cutting the Spin Art into circles and cutting on the edges of the paintings. More concentrating and cutting going on here! So our first creation was a group of flowers and a butterfly! Next, we kept thinking they looked like planets...so we created Our Universe! I created the circles into spirals to create snakes and added grass and detail with the scraps! From Putti Prapanacha... Egg Shaped Lanterns. Ever since we did our Tissue Paper Mache Eggs from a previous post I've been toying with this idea and have finally completed it. I really wanted the Tissue Paper Mache Eggs to be transparent, but we had to do a few layers so they did turn out beautiful, but they were opaque.
I was looking through Scribble Art a great kid's art book by Mary Ann Kohl and noticed an idea for the yarn eggs, but at the end of the idea it mentioned putting tissue paper over it for an extension. This was my light bulb moment and this is how these Egg Shaped Lanterns came to be!!! ILovehow they turned out! To begin, cut some 12 inch yarn pieces----about 8 pieces or so. Soak the yarn in the glue for a few minutes. Set a water balloon in a cup (I cut down a yogurt container to fit) and you are ready to wrap yarn around the balloon. Here is Cassie wrapping the yarn on the balloon. Here is our yarn wrapped balloon---we did 2 of these at a time! Now for the tissue paper part---make sure it is not bleeding tissue! Bubble Printing Fun!!! This weekend we were doing bubble activities galore: playing and printing with bubbles. Cassie enjoyed both. What inspired us to do this was when we were at friend's house and they had Crayola Colored Bubbles.
When you play with these bubbles they actually are colors. This was cool, but I will warn you that these colors get all over clothes and pavement/patios. Even though they are washable I would still wear old clothes. Well, we tried to make these bubbles with paint and it didn't work. (FAIL) (Crayola must have a secret ingredient!) First you need some water, tempera paint, and dish soap. We mixed about a 1/2 cup of water, 2 Tablespoons of paint, and a few squirts of dish soap in each container.
Then add a straw to each container and make sure you blow into the mixture. Once you have a huge bubble foam on the top of the container you are ready to lay a paper on top to print the bubbles. Here is our best bubble print.... we made lots and lots. I made the bubble prints into cards. The Chocolate Muffin Tree. I did a posting called Magnificent Magna Tiles when I first began my blog, but not many people have probably read it because I had few followers back then! If you want to check it out the post it is here and you can view some of the structures we have built with Magna Tiles!
Magna Tiles are one of our all time favorite toys! They are magnetic building toys that encourage Creativity, Math, and Science. They are expensive, but worth every penny because Cassie played with these every day for a year when she first got them! We started out with a long path made from square tiles and added a small ramp built with triangular tiles. We added another path with square tiles going perpendicular, but we needed to add a ramp there too. Cassie added a "rocket ramp"(the tall triangular structure) to the end of this pathway and she said the marbles could ride in the rocket!
Cassie added more rocket shapes to the structure. The marbles are rolling down! Inspiration: How to Make a Kaleidoscope for a Science Project. Fascinating Lamps by Calabarte | Pondly. Calabarte is the pseudonym of a Polish artist named Przemek Krawczynski, whose art takes on a peculiar but incredibly beautiful form: cool lamps. The name itself is a portmanteau of two words – art (obviously), and calabash, the fruit that carries his imagination. The calabash is a bottle gourd originating in India, although Calabarte gets his supply from Senegal. Due to ancient domestication and usage, the bottle gourd has an incredibly tough outer shell.
In the past, the gourd’s usage was defined mostly as a water container, due to having a tough, smooth shell with an ergonomic shape for handling, and natural buoyancy on water. Nevertheless, it’s edible both raw and cooked, and used in various cuisines. Due to the combination of dark, thick material with a light source within, the primary art of his work, however, shines in the dark. When he’s not making cool lamps, Calabarte partakes in a number of physical activities, enjoying life through sports, travelling, and making music. Latte Art – Charming Coffee Designs. Latte Art is a trend that has become popular several years ago. The secret is simple – you have to stir espresso and steamed milk creating charming surface pattern or even design.
Coffee foam art requires great skills but results are truly awesome. Today there are few international Latte Art contests where best artists (each of them is called “barista”) demonstrate their creativity and original performance. We thought that it would be a great inspiration for you people to see the collection of some of the most original examples of these amazing designs. Wikipedia: A barista (from the Italian for “bartender”) is a person, usually a coffee-house employee, who prepares and serves espresso-based coffee drinks.
Crystal Egg Geodes - Martha Stewart Easter. Geodes can be grown without using egg dye. The resulting crystals are clear to milky white, like quartz. While large chicken eggshells are suggested in this process, larger eggshells can be used. Simply increase the size of the plastic or glass container and double or triple the amounts of dye (1 packet), alum (3/4 part), and water (2 parts) used to create the growing solution. This Easter craft from Jim "Figgy" Noonan doubles as a science project, offering an opportunity to show kids the crystallization process at work. To make a fluorescent variation for Halloween, substitute the water and egg dye solution with glow water. Resources: If you don't want to blow your own egg or would like to try a larger eggshell, pre-blown shells are available from The Eggery Place.
