Impossible Triangle


An optical illusion uses patterns, color, and light to make images that confuse our brains. How does it work? Well, when our eyes gather information from the world around us, our brain’s job is to make sense of it. To understand what our eyes are seeing, our brains create something called a perception. But optical illusions actually cause our perceptions to be incorrect! They trick our brains into thinking we see something that’s not actually the true image.

Optical illusions are fun to explore! This activity highlights the optical illusion triangle. This is an object that can be drawn but cannot exist in 3-D form—it’s actually impossible!

Impossible Movement


Impossible Movement. Ball moves up a slope.

The visual trick involves a 3D construction of four slopes that appear to extend downwards away from a common centre (see video). When wooden balls are placed on the slopes, however, they bizarrely roll upwards as if a magnet is pulling them.

Dragon Illusion HueForge


This model was created using the original art found here Dragon-Illusion-BBC (thinkfun.com). Once printed, I heated the print along the marked lines with a heat gun that was set to 220c (if printed in anything other than ABS you may need to lower this temp). Once the plastic was soft, I folded the plastic to the correct position (may require some adjusting) I then put a little super glue on the three folded tabs. On it's own, this does not stand up too well. I just placed a little double sided tape under the tail and stuck to the table. You could easily super glue the tail down to a printed platform.

These 3D zoetropes create animations that look like real moving sculptures.
Note there are just 39 frogs not 40 - this is because once per revolution one frog jumps from one frame/segment into the next. This starts at frame J and finishes at frame A - where there is an A frog and T frog. There is only one A frog.
