This fun set of magic wooden blocks allows you to easily build a rainbow arch. No additional support is needed, such as magnets, screws or tapes. The rainbow arch comes as a 7 piece set or 9 piece set.

The wooden blocks are precision cut and sanded so that all blocks fit together neatly.

Watch the video below on how to stack the arch.

Materials Used

The wooden blocks are made from solid oak timber and are hand painted with VOC free wood stain. The stain is highly durable and does not colour transfer. The blocks have a semi-gloss finish.

Multiple Stacking Options

The wooden blocks can be stacked in two different ways both forming an arch. The long side and the short side of the blocks contain precision cut angles allowing you to make a large rainbow with the short end and a small rainbow using the long side of the blocks.

How Does it Work?

The rainbow arch is based on a century old principle of building arches that has been first applied in the roman empire. When building the rainbow arch the weight is evenly distributed among the pieces and when finished the blocks interlock with the middle block which is called the keystone (the green block).

Interchangeable Play Fun

The rainbow arch can be modified to hold other pieces within the arch as well. You can get as creative as you want and perhaps use some balancing blocks, boards or cars to stack. As the blocks interlock easily there are many options for you to get creative.
