WELCOME TO THE SCIENCE TOY MAKER HOME PAGE

All science toys and projects:

• *are accessible (so cheap to make that nobody is excluded because of cost, and they don't require special skills, tools, materials, or work facilities beyond a kitchen.).
• *have a "more about" page with explanations, related activities and high quality links for further research.
• *have clear step by step directions with lots of pictures. They have been thoroughly tested to work, yet also have the potential to be improved by creative inventors and tinkerers. Most project instructions have been improved by helpful feedback from people like you, and some projects are entirely the work of guest authors. Contact me
• *have a "science toy video preview" where you can see and hear the finished science toy in action (not all projects have this yet).
  
  My apologies: Some people don't like the garish colors (one friend compared it to an explosion at a Crayola crayon factory), and the pages are not print friendly. More about the site. Great reviewed links to other science project sites here.

• The QUICK AND EASY science toys below on this left side of the page are suitable for young kids, with a little help here and there. I make them with large groups of elementary age students. They generally take about half an hour to complete. Click on the project name or the picture.		 	The ADVANCED science toys below on this right side of the page require the maturity of teenagers and adults to build. I build them with my classes of middle school students. There are usually a couple of hours of work time involved. Click on the project name or picture.
  The MOVIE WHEEL and inventions like it ushered in the age of movies, then video. You can make pictures come alive.	What does the SNAKE CHARMER'S DUCK CALL have in common with saxophones and bagpipes?		The OVERHEAD WATER ROCKET LAUNCHER uses pressurized air and water to launch 2-liter bottle rockets.	The PUTT PUTT BOAT has a real candle powered  steam engine made from a soda can and straws.

  What makes the PROPELLER STICK spin mysteriously when you rub it. This is an easy version of an old folk toy that's also a great science toy.	Call it a VORTEX, whirlpool, tornado, hurricane, dust devil, water spout... whatever you call it, it happens a lot in nature.		When you combine origami with a hang glider you get a TUMBLEWING which is indoor air surfing.	This AIR ROCKET goes higher than the tallest trees.

  CARTESIAN DIVERS date back to the days of Galileo Galilee. It was so mysterious some people called it the "Devil's Diver."	They are as old as the hills, but there is something cool about TOPS. This one is easy to make and it writes patterns in its track		Got some old boom box, computer or stereo speakers? The RECYCLED SPEAKERS PHONE is an easy to make intercom.	ROBOT HANDS work like our real hands... with strings attached.

  This SPINNING BALLOON hovers mysteriously in the air, but it's not filled with helium.	I don't know what you will catch with it, but this MOOSE CALL demonstrates how accoustic string instrumants amplify sound.		How does this ingenious BANGLADESH TWINE SPINNER twirl so fast?	This is NOT A POPGUN and I'm not going to show you how to make it...unless you overwhelm my security by clicking.

  The OSCILLATING WOODPECKER is another timeless folk toy, now easy enough for kids to make.	Alternately pull the strings and the CLIMBING CREATURE shimmies up. Yet another old folk toy that will never go out of date.		Make rubber band powered AIRPLANES from scratch, even the props. They fly great.	Is this simple electronic project a LIE DETECTOR or not? Click for the truth.

  The MAGNETICALLY LEVITATED KANGAROO (or is it a rabbit?) bounces on a magnetic cushion.	The ROBOT FINGER is easier to build than the ROBOT HAND and still demonstrates how tendons work.		This HELICOPTER soars over trees when you yank on the string, putting aerodynamic theory to work.	It's not high-tech, but whistling on an ACORN CAP involves some cool science.

  9 year old guest scientist Shane shows us how to make a simple RUBBER BAND BALL	Under Construction: guest article: How to Build an Electroscope and more about static electricity		When you pull the string down, why does the DRAGONFLY WITH MECHANICAL ADVANTAGE go up?
  A homemade PARACHUTE is a classic science toy NOT READY, UNDER CONSTRUCTION	You don't need a submarine to make a PERISCOPE.		These TIGHTROPE CYCLISTS make it look easy. Actually, it's the science of balance that matters.	GIANT WATER PRISMS bend light and separate the colors out of white light. They are also hilarious to look through.

  What does a slide set about village technology in the South Asian country of Bangladesh have to do with science toys? Quite a lot, actually. Click here and see if you can figure out the connection.			New! Appropriate Technology/Alternative Energy Association here.
