All Washed Up

When it come to busting up grease and dirt, few things work better than soap, thanks to the amazing structure of soap molecules! These molecules work by having two very different sides. One side is an oxygen (O) ion loosely hanging on to a sodium (Na) or potassium (K) ion. An ion is an electrically charged atom or group of atoms. Because this end is very similar to water molecules (H2O) it can mix well with water. The other end is a long chain of carbon and hydrocarbon (H) atoms linked together.

Why I am a Maker

Last year I jumped at the chance to have a booth at the first ever Portland Mini Maker Faire at OMSI. Having just published a book earlier in the spring I knew the faire would be a great opportunity to demonstrate some of the crazy projects I’d come up with and sell the book itself. This was the first time I’d done a festival so I wasn’t exactly sure what to expect. OMSI held a couple planning meetings for us which really helped me wrap my head around the prep work.

For the Love of Time

On a given Saturday at the museum you may encounter a group of avid tinkerers in the Turbine Hall.

The local chapter of the National Association of Watch and Clock Collectors (NAWCC 31) has had a long relationship with OMSI. For almost two decades the group has been coming to OMSI to maintain and repair the antique Oregonian Clock in the Turbine Hall mezzanine.

Members share a love of both timekeeping and community service. Some are collectors and hobbyists; others repair clocks and watches for a living.

Playing with Senses

In Science Playground, we love to keep our senses engaged and our minds open to exploration by playing with sensory materials such as flubber and playdough. If you have been to our space at OMSI, you might have noticed that we are not the only ones interested in playing with these types of materials.

Hot Hands, Instant Crystals, and Super Cool Solutions

As the weather gets colder, fingers get frosty. Most chemical hand warmers are single use and take a while to warm up. But it's easy to make an instant, reusable hot pack with two simple ingredients: baking soda and vinegar. Follow the recipe below to make your own at home!

Materials:
  • 1 cup white vinegar (acetic acid C2O2H4)
  • 5 level teaspoons of baking soda (sodium bicarbonate NaHCO3

A-TAC: OMSI’s Teen Maker Movement

Build. Break. Make. Indeed. OMSI and Multnomah County Library’s Awesome Teen Advisory Council (A-TAC) demoed their inventive hearts out at Portland’s first Mini Maker Faire.

The teens used MakerBot Replicators to 3D print mustache rings and space invaders, and an EggBot to personalize ping pong balls. Let’s just say visitors to the A-TAC table did not walk away unhappy. Over 5,000 visitors came to OMSI to view the many inventions on display.

What the heck IS Maker Faire?

Ever since we announced the Portland Mini Maker Faire, the two responses I most often get are "YES, finally!" and "What the heck IS a Maker Faire?" Folks who have been to a Maker Faire in the past or even just heard reports know Portland is a great town to host one, and sure enough nearly all the makers we're showcasing this weekend are from the Pacific Northwest. But those who haven't heard of Maker Faire may need a little background.

Hand-Eye Supply Getting Geared Up for Portland Mini Maker Faire

Core77's Hand-Eye Supply store is proud to be a part of Portland's emerging maker culture and we couldn't be more thrilled about the upcoming Mini Maker Faire at the Oregon Museum of Science and Industry. As media sponsors for Portland's Mini Maker Faire and the upcoming World Maker Faire in New York City, we are enthusiastic supporters of the World's Biggest Show and Tell.

So excited for PDX Mini Maker Faire, local crafter can’t sleep at night

Similar to the medieval markets of a well fortified village, craftsmen, artists, builders and people who know the business end of a trebuchet are getting together in just a few weeks to show off their mad skills. Unlike the good old pre-industrial age, though, this faire has a decidedly tech inclination, with robot builders, Arduino programmers, 3D printers and a whole mess of folks who do cool things with LEGO bricks demonstrating what their eclectic organizations and businesses are up to.

Cooking Up Science: Ice Cream, You Scream!

As hot weather creeps towards Oregon, the thoughts of many turn to usual summer pastimes: swimming, hiking, barbeques, and of course, ice cream! Beyond the love affair with our taste buds, there’s a lot of cool science behind this sweet treat. Keep reading to learn what makes ice cream so sweet and smooth, and how you can make it at home without any fancy equipment!
