Where do you put the oil? What does a do-it-yourselfer do with the used crankcase motor oil when it has been removed from the vehicle? In the interest of controlling pollution and in not upsetting our ecology, I’m curious as to what POPULAR SCIENCE recommends for this practice.

The New Yard Tools That Finish the Job
Can gardening be fun? Yes, if you use the new labor-saving tools on backbreaking jobs

E. F. LINDSLEY
Ten to one, by midsummer your lawn will have power-mower scruff— a look of cut but unkempt raggedness. Like most of us, you probably mow one gear too fast. You don’t have time to creep, back, and cramp to get in tight, so you leave a scraggly margin of unsightly rank growth around trees, foundations, curbs, and posts.

“By 1976, eighty percent of original-equipment tires in America will be of radial construction,” predicts Firestone’s Andrew Rodger Jr. Firestone has just added several new radiais to its product line: Mini-Sport Radial for small imports, Steel Belt Radial for compacts, and the Radial V-1 for full-size cars.

NEW SPORTS IMPORTS: Tops in Braking and Handling
We call them sports cars, but their space, versatility, and finish qualify them as family cars, too
How PS tests cars—and what the tests show
[no value]

JAN P. NORBYE
One look tells you they’re sports cars. Or perhaps you prefer to call them GT ( Grand Touring) coupes. Both labels fit perfectly. The three cars set new records in our braking and handling tests, accelerated right along with some of the biggest American V8s you can buy, and surprised us with their gasoline mileage.

TIC TRACER -Tells You Which Wires Are Live

W.J.Hawkins
The fastest way to find a hot wire in a maze of others is to touch it. A safer—if slower—way is to use a volt meter or an indicator lamp. Now there’s a third tool, faster than a meter and less painful than a finger. It’s called Tic Tracer and that’s exactly what it does—ticks as it traces an AC electrical field.

Five animal species that seemed on the verge of extinction not too long ago have made dramatic comebacks and may be out of danger, according to Dr. Carl L. Hubbs, a marine biologist with the Scripps Institution of Oceanography. The animals, which include some of the most fascinating mammals on Earth, are the gray whale, sea otter, northern elephant seal, and two species of fur seal.

Chrysler will make sure that none of its ’73 cars produces over 84 db of noise at wide-open throttle. To meet the goal, the company has changed intake and exhaust systems. The cars will be quieter inside, too. Better seals along the beltline will cut much of the noise entering through window joints.

JAN P. NORBYE
Take a brand new $250,000 automobile. Load it with dummy passengers. Then drive it into a wall at 50 mph. The same with a second car. A few more—11 in all—ram into the wall so there’s nothing left but a tangle of very high-priced metal and plastic—and one thing more: a basis for the know-how that will let you walk away from a “fatal” crash.

With 50 million cameras around the world shooting Kodak or Kodaklicensed Instamatic cartridges, you’d think those folks at Rochester, N.Y., would be satisfied. Not so. A few people, somewhere, haven’t been taking pictures. Claim cameras are too big, or too nuisancy to carry.

Fail-Safe Tire Lets You Drive at Speed After Blowout
Incredible but true: go 50 mph for a hundred miles— safely—on a flat tire
[no value]
[no value]
DAVID SCOTT
Ever try cornering hard at 50 mph with a flat outside front tire? I did, and accelerated out of the bend to barrel down the following straight. It was at a race track in southern France near Marseille, where Dunlop recently unveiled its “total mobility tire.” This breakthrough in tire design aims to take all the hazard out of a blowout at speed, to remove the inconvenience of a simple puncture or slow leak, and to let you drive on safely at near-normal speeds for up to 100 miles.

Frank M.Butrick
Here’s a quick way to make your pool filter mobile—a portable cart. You can store it in your garage or yard shed during the winter and won’t have to worry about having it damaged or stolen. Any filter weighing less than 100 pounds can be easily mounted on an inexpensive rubbish-can cart.

That Versatile VOM— Now It Troubleshoots Your Car
Keep running costs down by keeping performance up with these sure-fire checks
[no value]
[no value]
RICHARD DAY
There’s a real tiger for troubleshooting and maintaining the ignition system of your car—and you can own it for $20 or less. It’s a volt-ohm-milliammeter—VOM for short. With a VOM you can make go/nogo checks of primary wiring (nontransistorized ignitions only), coil, distributor points, spark cables, ignition switch, ground circuit, distributor cap, rotor, built-in primary resistance, and more.

Wireless Burglar Alarm Works in a "Flash"

Doug Garr.
Saturday-night thieves will have a tough time foiling this one. Defensive Instruments, Inc., borrowed Sylvania’s Magicube camera flash and ended up with Flashguard—an ingenious, low-cost, burglar-alarm system. There’s no need to install extensive wiring as with other alarm systems; four D-cell batteries power an alarm bell.

Sears makes a direct appeal to do-it-yourselfers in its ’72 autoparts catalog. A statement on the cover says: “If you’ve been hesitating about installing auto parts yourself, this catalog might change your mind.” Instructions inside include checking plugs, points, rotor, and gap, using a dwell tachometer, and checking timing.

Make a Trio of Sturdy Stack Tables

Harry Sherman
The $75 price tag on a trio of stack tables I saw in a furniture store sent me home with a resolve to make my own set. As it turned out, I saved $65, and I ended up with sturdier tables than those in the store. The tops are plastic-laminate sink cutouts (a local cabinet shop will often sell you these at low cost).

J. C. SPANGLER Sr.
Ask any successful wildlife photographer the secret of getting good pictures. He’ll tell you it’s getting close to your subject. One of the best techniques I’ve found for getting close to birds and other animals is to work from a tree perch.
