Looking for an inexpensive pyramid to do experiments with? Well, this is it! These fold-up cardboard pyramids are made from heavy-duty 275 lb test cardboard, precision cut to the same 51.83 or 72 degree slope angles as my other Giza and Nubian pyramids and held together with super-strong Gaffer's tape, a high-quality duct tape made out of cloth. Designed to be firm and steady when placed on a flat surface, but folds up easily and quickly when not in use, and has no metal in it whatsoever.  Most of the well-known pyramidologists, including Patrick Flanagan, Max Toth, Antoine Bovis, and Karel Drbal all started with cardboard pyramids and achieved impressive results. Use for experiments, including testing to see if it can energize water, preserve food, grow larger sprouts, invigorate garden seeds, enhance the flavors of foods, and even sharpen razor blades!​

Ideally, align your pyramid to either true north or magnetic north. After assembling, refer to the Alignment page for specific details.​
