Wie die Fotografie begann

Mit dem Experimentierkasten Camera Obscura von Kraul tauchen Kinder ab 10 Jahren (mit Unterstützung bereits ab 8 Jahren) tief in die Geschichte der Fotografie ein – und werden selbst zu kleinen Erfinder:innen! Der Bausatz vermittelt auf faszinierende Weise das jahrtausendealte Prinzip der Lochkamera und weckt Neugier auf Technik, Geschichte und Naturwissenschaft.

Schon Aristoteles beobachtete mithilfe der Camera Obscura Sonnenfinsternisse, und auch große Denker wie Goethe experimentierten mit dem magisch anmutenden Spiel aus Licht und Schatten. Die Camera Obscura, auch als „Lochkamera“ bekannt, war über Jahrhunderte hinweg ein wichtiges Werkzeug für Künstler, Forscher und schließlich Fotografen. Bis heute ist ihr Grundprinzip in jeder modernen Kamera enthalten.

Mit dem Kraul-Baukasten können Kinder ihre eigene Camera Obscura bauen und erleben, wie durch ein kleines Loch und eine Linse ein umgedrehtes Bild auf Transparentpapier projiziert wird. Die beiliegende Anleitung erklärt nicht nur den Zusammenbau, sondern auch die Hintergründe und Anwendungsbeispiele – für eine spannende Entdeckungsreise in die Welt der Optik.

Effective temporary fix
Style: 18oz, Style: 18oz
The slim brand has always been an genuine effective fix. I have been using slime since I used to ride on bicycles. Well it is not a permanent fix for if you have a hole in your inner tube it is a great fix to hold you over until you are able to get to either the mechanic or to your local store to get a replacement inner tube. Overall, it's worth every penny and you get plenty in the canister that it comes in depending on which slime you are getting whether that's the plastic bottle for your inner tubes for a bicycle or the metal canister as I've shown in my picture for your SUVs trucks or vans. However I don't give this an entire five stars but more of four stars not because of their product but because resorting to using slime rather than fixing the problem is more of my own problem. ⭐⭐⭐⭐ 👍👍

Don't buy doesn't work
Style: 18oz, Style: 18oz
Terrible did nothing. Even tried to let wheel turn 360 degrees yet the solution get in the tire leak proper. Directions on can differ from instructions on here/Amazon. I followed directions on can EXACTLY and still didnt even hold one PSI of air. I'd be better off burning the $10 for warmth rather then waste it this way

Amazing stuff
Style: 14oz
I’ve been using this stuff for a number of years for a number of vehicles now and it works every time. It’s especially great with those small annoying leaks where you just lose a couple pounds every few days so you have to keep adding air like once a week. It totally seals it. The bottle says to only rely on it for 300 to 500 miles and then get a proper fix. However, I have not found this to be the case. The seal holds for the rest of the life of my tire every time I’ve used it. My only complaint is that I wish it was a little cheaper, but you can seal up 2 tires (use only half the can per tire - you can probably even get away with using less). There is a garage not far from me that fixes leaking tires for $10, which is the same price as this product so not really saving any money by using it. It’s more just a matter of convenience. Just make sure you get this “thru-core” one. They have other ones as well so it can get confusing, but the one you’d want for situations like I’ve described above (small to medium leak in a typical passenger vehicle) is this “thru-core” one.
