Back by popular demand is the Hughes Wave Motion Machines "WaveChain" Keychain. I have not produced these since 2012 when they were a hit with adults and kids alike. Gently tilt the 4 inch vessel from side to side and watch the cool wave patterns form. These make great little stocking stuffers! The side of the keychain has my website printed on it in case you'd ever like to purchase a Model One Wave Motion Machine or more WaveChains. Buy more and save!
