This idea came from the Best of Beakman\u00e2\u20ac\u2122s World<\/em><\/a> videos. Our son started watching them because I told him he wasn\u00e2\u20ac\u2122t going to be sitting in front of the TV all summer.<\/p>\n

He negotiated: Even if it\u00e2\u20ac\u2122s educational? What about Beakman\u00e2\u20ac\u2122s World<\/em>? And Liberty\u00e2\u20ac\u2122s Kids<\/em>?<\/p>\n

My counter: Okay, you can watch Beakman\u00e2\u20ac\u2122s World<\/em>, but you have to do some of the experiments, too.<\/p>\n

Son: And then I can watch Top Gear<\/em> and Mythbusters<\/em>.<\/p>\n

1. Cut a hole big enough for your<\/em> head to go through a large box, slightly forward of center.*<\/p>\n

2. Tape a piece of white paper on the panel furthest from your head-hole, on the inside of the box. See it (above photo) back there?<\/p>\n

$\"CamObsc2\"$ <\/a><\/p>\n

3. Tape up ALL the seams with a light-blocking tape like masking tape, or the ever useful Duct Tape<\/a>.<\/p>\n

$\"CamObsc3\"$ <\/a><\/p>\n

3. Wrap a towel around your child\u00e2\u20ac\u2122s neck, and place the box over his head. Check for stray light; if he sees any, repair it.<\/p>\n

4. After<\/em> removing the box from your child\u00e2\u20ac\u2122s\u00c2\u00a0 head (muy importante, \u00c2\u00bfno?), use a nail to poke a small hole in the panel opposite from the white-papered side.\u00c2\u00a0 Poke the hole higher up than the level of your head.<\/p>\n

$\"CamObsc4\"$ <\/a><\/p>\n

5. Re-wrap the towel, replace the box over head (so that the boxed-person is facing the white paper) and observe the upside down images of whatever might be taking place behind you.<\/p>\n

$\"CamObsc5\"$ <\/a><\/p>\n

We personally enjoyed the outdoor images best. The above photo was collected by placing our camera INSIDE of the box and remotely snapping the picture. (It\u00e2\u20ac\u2122s a photo of tree branches and leaves).<\/p>\n

*Not a typo. Make it big enough for YOUR head. You\u00e2\u20ac\u2122ll want to check it out.<\/p>\n

How does it work (simplified)?<\/p>\n

We see things when light bounces off of them. The light bounces off in every direction.<\/p>\n

When the light bounces off of Dancing Dad, a tiny bit gets through the nail hole in the cardboard box, and we see that reflected light as a reversed (and pretty dim) image on the white paper taped inside of the box:<\/p>\n

This is exactly how a pinhole camera works, and I urge you to check this site out<\/a> if you\u00e2\u20ac\u2122d love a great summer project:<\/p>\n

Take it to a whole new level, and turn your whole bedroom into a camera obscura \u00e2\u20ac\u201c just block all the light coming into your room except for a small hole from the window, wait for your eyes to adjust, and watch the opposite wall\/ceiling to see what\u00e2\u20ac\u2122s going on outside:\u00c2\u00a0 from http:\/\/commonsensephotography.com\/camera_history_and_a_light_concept\/index.php<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
