Match Stick Rocket SUBJECT: Rocketry TOPIC: Propulsion DESCRIPTION: A small solid propellant rocket is made from a match and a piece of aluminum foil. CONTRIBUTED BY: Steve Culivan, KSC EDITED BY: Roger Storm, NASA Glenn Research Center 2 match book matches or wooden stick matches Small square of aluminum foil Paper clip Safety pin Take one match and wrap a small piece of aluminum foil around the match-head. Caution: Be sure the match rocket is pointed away from people or burnable materials. it is recommended to have water or some other fire extinguishant available. DISCUSSION: The match stick rocket demonstrates Isaac Newton's Laws of Motion as they relate to rocketry. In an interesting variation of the experiment, try making holes of different diameters to let the combustion products out at different rates.

Crazy Domestic: Melted Snowman CookiesI saw a picture of these the other day on Allrecipes.com and thought it was such a cute idea, I had to try it. After googleing it, I found a good tutorial on Stacy's Sweet Shop. I modified a few things to make it more simple for me (less homemade more store bought). To see the original Melted Snowman Cookie, and meet the inventor herself, go check out Meaghan (great name) @ The Decorated Cookie! Here's what I used: •1 package Betty Crocker Sugar Cookie Mix•10 large marshmallows•Betty Crocker Cookie Icing (white and orange)•Wilton Decorating Icing Tubes in Black, Red, Green, Blue and Pink***it would have been a lot cheaper if I had just made the icing myself, see Stacy's tutorial for a good recipe)*** Here's what I did: •Mix cookie mix according to directions, or prepare your favorite cut out sugar cookie recipe, then just grab a golf ball sized chunk and squish it down until it's about 1/4-1/2 inch thick.

Disable All Notification Balloons in Windows 7 or VistaIf you find the popup notification balloons in the Windows system tray to be too annoying, you might be interested to know that you can completely disable them. This would be an extreme option, of course… typically you can just turn them off in any offending applications, but if you want to disable them across the board, this is the solution. Note: This should work in any version of Windows. Note: I’m not necessarily recommending that everybody do this… you should only bother with it if you need to solve this particular problem. Manual Registry Hack Open up regedit.exe through the start menu search or run box, and then browse down to the following key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced Right-click on the right-hand pane, and create a new 32-bit DWORD with the following values: Name: EnableBalloonTips Value: 0 You’ll have to logoff and back on in order to see the change… or to be more correct, you won’t see any popup balloons anymore.
LCD Calculator - Least Common DenominatorLeast Common Denominator Calculator Use this calculator to find the least common denominator of fractions, integers and mixed numbers. We also have calculators for least common multiple, fraction operations, simplifying fractions, mixed numbers operations, and comparing fractions. See additional notes below. How to Find the LCD of Fractions, Integers and Mixed Numbers: To find the LCD first convert all integers and mixed numbers (mixed fractions) into fractions. Steps to find the LCD of fractions, integers and mixed numbers Convert integers and mixed numbers to improper fractions Find the LCD of all the fractions Rewrite fractions as equivalent fractions using the LCD Example using this calculator default sample: Input: 1 1/2, 3/8, 5/6, 3 Convert integers and mixed numbers to improper fractions 3/8 and 5/6 are already fractions so we can use those as they are written. 1 1/2 is the same as (1/1) + (1/2).

Greek Gods Family Tree / Genealogy | ludios.orgludios.orgHow to Buld a Pond - Build Your Own Backyard PondIf you've always wanted a backyard pond, you're not alone. Hundreds of thousands of homeowners already have them and thousands more are installing them every year. Why all the fuss over a water-filled hole? Well, for one thing, gurgling waterfalls are inherently appealing. But before you can start stocking aquatic plants and animals, such as fish, frogs, tadpoles and snails, you need the pond itself--and a source for supplies and equipment. Keep in mind that the project doesn't have to be huge. Digging It Once you've chosen a location for the pond, lay out the perimeter using rope or a garden hose. Now, line the hole and the pit with screened mason's sand and rake it smooth. Laying Rubber Fold the rubber liner lengthwise, center it over the hole and unfold it. We built this pond out of red New England fieldstone, which is relatively flat and easy to stack. Start stacking stones on the pond floor, also called the plant shelf (to differentiate it from the pump pit).
you knew i was going to make one.they are all over pinterest....(i still am not signed up for pinterest because i don't have time for one more thing but browsing is fun!) so we made one. i took a box of 64 crayons and took out the blacks and browns.i used another small box and doubled up on the good colors i liked and hot glued them to the top of our canvas. then we turned our blow dryer to hot on high. not long after you set the hair dryer by the crayons they get shiny and then the wax starts to melt! and it dries really quickly too. seriously. what could be happier than this?? GREAT project. loved it today is the first FULL day with ALL my kids in ALL day school.yeah...i am smiling as i type that. it's good. it's quiet. i am rockin' it. removing wallpaper.....making code for craft weekend stuff.....doing my hair....going to lunch..... it's all good. hooray for school!
Slappy Landings: The slingshot waterslide that flings you 120ft through the airBy Daniel Miller Updated: 12:00 GMT, 2 September 2011 These thrill-seekers are enjoying the wettest and wildest ride of their lives, hurtling 120ft through the air after launching themselves off the world's most extreme water slide. The fearless dare devils first climb into a inflatable ring which is dragged down the rubber track at break-neck speed by a powerful quad bike. When they hit the jump at the end they are sent flying high into the air before crashing down into the river. The amazing video was shot in Paradise, Utah, by clothing company Vooray to promote their merchandise. Three people have been left unconscious by the force of hitting the water, so please, don't try this at home! Scroll down for video Down we go: Another brave adrenaline junkie sets off down the slide in an inflatable ring Lift off: Still clinging to the inflatable he's sent rocketing into the air Air time: He goes head over heels hurtling across the river Rapid descent: Holding his nose he prepares to hit the water
