Bert's Quarter Shrinking Gallery


Small tube electromagnets with very large power discharges make for a way to magnetically crush coins placed inside the tube. Bert's gallery has a selection of photos and description of the shrinker and a larger collection of photos of the effects.

Japanese Toy to Make Records


This started out as a post about a new toy available in Japan to make audio records (as in "gramophone") on CDs and other flat discs, and branched off to include some other related ideas. I want one of those toys.

2020 update: the company that made those toys, Gakken, went on to produce several other kits, including record recorder / players that use plastic cups and candles as the media. Here's a "how to" on assmebling the plastic cup version: Building the Gakken Cup Phonograph Kit.

I did eventually find the CD recorder and the plastic cup recorder available for sale in San Francisco's Japantown. I purchased, assembled, played with, and gave them away (probably to SCRAP, the Scaveger's Center for Recycled Art Products (or some such name)).
