Halley's Comet Game directions and play rules
Directions for a paper game. Cut out the Halley’s Comet figures and small red circles, mount on cardboard, and play with two to four players. Players toss circles to earn moves, advance the comet along the orbit from Start toward Finish, with detours for Earth and Mars circuits as indicated, following yellow spaces. The first to Finish wins.

Coating Steel With Copper Achieves Surface Bonding
A steel billet is immersed in a bath of molten copper at high temperature until the surface layer partially dissolves and blends with the copper coating. The process aims for a durable copper steel composite.
Copper Iron Bonding in Billet Casting Process
The outer portion of the steel billet is impregnated to form an alloy film of copper and iron. After withdrawal the surface bears the alloy film, then a mould step coats the assembly with pure copper. The final copper layer welds to the alloyed surface, uniting the metals to endure abrupt temperature changes and mechanical stress.
Cement for Wine Tanks Lengthy storage tanks lined with glass squares
Experiments using cement for wine storage tanks show unlined concrete walls absorb wine aromas as acids decompose the cement. Acid-proof coatings fail, but a lining of small glass squares set in cement mortar resists acids and preserves bouquet. Tanks range from 530 to 66 000 gallons and suit cottonseed storage too.
Power of Sea Waves Measured by Italian Engineer
Riccardo Salvadori reports experimental results on sea wave power not tides. He finds horsepower varies with wave height, with a table showing higher waves yield more power. A wave power plant would cost about $1000 per horsepower.
