			# Set out the tops on the table. If the event has over 400 guests, have a plastic bin on the table for the students to spin the tops in.
	1. ~~Steps~~ for the ~~demonstration~~.		# Allow students to come up to the table and spin the tops. Have them try to identify the source of the illusions they see on the tops when they are spinning.

	2. ~~Be sure~~ to ~~clarify~~ on ~~steps about any safety equipment needed.~~

	~~3. Make sure steps can be understood by a first-time reader~~.


	== Why This Works ==		== Why This Works ==

	~~===Short Explanation===~~		This demonstration is focusing on the effect known as Temporal Aliasing. ''Temporal Aliasing'' is when an object is moving quickly, or an image is changing rapidly, and the motion is too fast for our eyes to follow. Our brains then receive the blurred image, and try to process it as a non-blurry image. The result is that we "see" a pattern, color, or motion that isn't actually there. The tops are known as Benham's Tops, and were originally made by a toymaker in the early 20th century. The effect that is seen on them is based on how quickly the tops are spinning. If the tops are spinning fast, then they will have distinct circles on them and a greater color change. If the tops are spinning slowly, then the lines are blurry, and there might be some mild color change seen on them. The tops with a solid black side, however, have a unique feature due to our eyes. Everyone's eyes are slightly different, even when it comes to the number of images, or "frames", we see per second. On average, we can see 60 frames per second, but individually we see either slightly more or slightly less than that. The tops with a solid black side, when spinning, create a color illusion based on how long the black lines appear to be. Since our eyes all see slightly different numbers of frames, we will all see different shades of colors in the lines!
	This is ~~where you would provide a basic~~, ~~easy-~~to-~~understand explanation of the demonstration~~. ~~Try not to use too much~~ "~~Science Jargon~~", and ~~if needed add any explanation tips, like comparing~~ the ~~demo to something kids~~ are ~~familiar with~~.

	~~===Full Explanation===~~
	~~This is where you will explain~~ the ~~demonstration in full~~, and ~~provide all additional information that pertains to the demo~~. ~~Unlike~~ the ~~short explanation above~~, ~~this should be worded so someone who is familiar with~~ the ~~topics might understand it. If needed~~, ~~you can provide equations~~ and ~~citations for additional sources of information~~ on ~~the topic~~. ~~This is also where you will find some answers for trickier questions~~, ~~such as "How does~~ a ~~plane fly upside-down?" for the Bernoulli~~'s ~~Principle demo. If you want~~ to ~~add a floating box for equations~~, ~~copy the following:~~

	~~{\| class=~~"~~wikitable" style=~~"color:black~~; background-color:#ddd; text-align: center; margin: auto"~~
	~~\| This will give you~~

'''''WRITEUP UNDER CONSTRUCTION'''''

== Materials ==

* Set of Tops

== Safety Precautions ==

Please read the General Safety section of the [[Demonstration Safety]] page before performing this demonstration.

== Demonstration ==

1. Steps for the demonstration.

2. Be sure to clarify on steps about any safety equipment needed.

3. Make sure steps can be understood by a first-time reader.

== Why This Works ==

===Short Explanation===
This is where you would provide a basic, easy-to-understand explanation of the demonstration. Try not to use too much "Science Jargon", and if needed add any explanation tips, like comparing the demo to something kids are familiar with.

===Full Explanation===
This is where you will explain the demonstration in full, and provide all additional information that pertains to the demo. Unlike the short explanation above, this should be worded so someone who is familiar with the topics might understand it. If needed, you can provide equations and citations for additional sources of information on the topic. This is also where you will find some answers for trickier questions, such as "How does a plane fly upside-down?" for the Bernoulli's Principle demo. If you want to add a floating box for equations, copy the following:

{| class="wikitable" style="color:black; background-color:#ddd; text-align: center; margin: auto"
| This will give you
| a floating box.

| The box will be
