Purple Pasted, Plainjane Fresh Gymchalk Blocks with Pasted Reforms

In the video, the creator explores three different brands of gym chalk blocks. The first two plain blocks are CFD, the next two plain blocks are unbranded from AliExpress, and the pasted blocks are Edelrid. The creator recounts discovering the CFD blocks unexpectedly, describing the excitement of finding them in a heavy box. The unbranded blocks each have a unique texture and sound. The Edelrid pasted blocks are tested for breakage, and the creator softens them using a water‑brick freeze‑and‑cook method. The video also explains what gym chalk is, its uses, and how it differs from school chalk, emphasizing that it is made from magnesium carbonate and is not edible.
