Vintersporta med Gutenberg

 Att lära sig att göra kartor, snickra, fotografera och andra roliga saker, var 1915 förbehållet gossarna. Flickorna hade i bästa fall bröder som lät dem följa med på kälkturer.

Men i dag, när vi vet att tjejer kan, är det ju inget som hindrar alla från att läsa den här härliga boken, och prova somliga (eller alla) av bokens projekt. Här, i "The Boy Mechanic, Book 2", finns inte bara stora projekt som kälkar, grindar och isjakter — det är gott om idéer för mindre saker, trollerikonster och sådant jag tycker mest liknar husmoderstips.

 Coaster bobs usually have about the same form of construction, and only slight changes from the ordinary are made to satisfy the builder. The one shown has some distinctive features which make it a sled of luxury, and the builder will pride himself in the making. A list of the materials required is given on the opposite page. Any wood may be used for the sled, except for the runners, which should be made of ash.
Det här är en sådan där bok där jag får lägga band på mig för att inte citera hela boken.

Mind-Reading Effect with Cards

Five cards are shown, and some one person is asked to think of two cards in the lot, after which the performer places the cards behind his back and removes any two cards, then shows the remaining three and asks if the two cards in mind have been removed. The answer is always yes, as it cannot be otherwise.
To prepare the cards, take any 10 cards from the pack and paste the back of one card to another, making five double cards. Removing any two cards behind the performer's back reduces the number of cards to three, and when these are turned over they will not have the same faces so that the ones first seen cannot be shown the second time even though all five cards were turned over and shown.

Bend a piece of wire in the shape shown in the illustration and attach it to a spool of thread. The ends of the wire should clamp the spool slightly and the loop in the wire will keep it from rolling. Place the end of the thread through the loop in the wire and it will not become tangled.—Contributed by J. V. Loeffler, Evansville, Ind.

Automatically Extinguishing a Candle

Candles can be easily fitted with attachments to extinguish the light at a set time. To determine the length of time, it is necessary to mark a candle of the size used and time how long a certain length of it will burn. Then it is sufficient to suspend a small metal dome, or cap, to which a string is attached, directly over the flame, and run the opposite end of the string over nails or through screw eyes, so that it can be tied around the candle such a distance from the flame end, that the part between the flame and the string will be consumed in the time desired for the light to burn. When this point is reached, the string slips off the candle, and the cap drops on the flame.

Floor Push Button


An ordinary electric push button can be used for a floor push button by placing it on a bracket or shelf attached to a joist, as shown, and using a nail for the extension push. A 1/4-in. hole is bored through the floor, also through a small piece of wood fastened beneath the floor, at the right place to direct the nail so that it will strike directly upon the small black knob of the push button. The nail should be just long enough to rest lightly on the knob.—Contributed by Reginald R. Insole, Hamilton,

  1. Mycket praktiskt och användbar information. "Slädtåget" påminner om de sparktåg vi brukade göra som barn. En lång rad sparkar hopflätade på längden och så full fart utför backen. Det brukade gå bra...

    Och det självsläckande ljuset ser ju mycket genomtänkt ut. Får nästan lust att pröva!

    1. Karin,
      Vet inte om jag ska varna dig för att läsa boken, eller rekommendera den. Risken eller chansen att du vill prova på det mesta är överhängande! Och 995 bilder finns det att titta på!
