HABA Big Optics Workshop

The blocks are a great and fun way for young kids to see the amazing optics effects. My personal favorates are the mirror block that shows upside down image (but you can also easily do this with a spoon),the spinning tops and the faceted block.

The color blending block are fun, but the plastic is so thick that the colors don't blend well the 3 colors are blue, pinky red and very orangy yellow, so when you put the blue and red together, you don't get purple, but a somewhat dirty pink, no orange or green for the same reason. The colors blend a bit if you put the block right infront of your eyes.

The prism alone is great, but not so good on the "Designed purpose" haba gives you some cards with left and right slightly different, and if you use the prism to cover the right, you see the left side as a whole image (from the card and through the prism). But you have to make sure the prism covers exactly the right side, or the bear will have 2 noses or no nose at all it's so difficult for little hands to master and even for adults, it's frustrating.

It has 10 or 11 items/sets and I will probably pay $30-40 max for this. I got this somewhere else when it was on sale within the price range. I will never pay 70 bucks for this.

My three year old son won't let me put this optics set away! Each peice has something unusual about it that catches his eye. The top comes with interchangeable disks that have a different optical illusion when spun. The cinema block animates a bird and a worm. The concave mirror makes things appear upside down or smaller and bigger. There are a couple of blocks that play tricks on your eyes, a durable kaleidoscope, a block that allows

A child to blend colors and look at the world through them. There is also a prism, a faceted lense block and some animal cards. The best thing about this set is that even though each peice is unique, a child can combine the peices in ways in which they can discover more unusual effects. Fun, fun, fun, even for mom and dad.
