Stirling-Motor mit Teelichtantrieb Dampfmaschinen waren die ersten Motoren, die den Menschen schwere Arbeiten leicht machten. Allerdings gab es häufig Explosionen in den Dampfkesseln. Darum bemühten sich viele Ingenieure, weniger gefährliche Antriebe zu erfinden. Der junge schottische Geistliche Robert Stirling entwickelte vor fast 200 Jahren eine Motoren-Art, die bisher nie im großen Stil, aber doch in etlichen Anwendungen genutzt wird. Der kleine Motor entsteht buchstäblich aus der Dose, in der er verpackt ist. Angetrieben wird er durch die Wärme des Teelichts und die Luftkühlung am Arbeitszylinder. Das Prinzip ist ganz einfach, doch sehr raffiniert: Verdrängungskolben und Arbeitskolben schieben aufgrund der Erwärmung und Abkühlung die Luft zwischen den beiden Zylindern hin und her. Dadurch kann der Arbeitskolben den Propeller antreiben. Für den Zusammenbau der ca. 150 Teile brauchen Bastler 2-3 Stunden. Die gründliche Anleitung mit exakten Bildern führt Schritt für Schritt zum fertigen Motor. Es sind nur einfache Werkzeuge nötig.

Heavy chewer approved.
Style: Ball, Size: Medium (Pack of 1)
My pomsky will destroy a toy in minutes. Ropes, and the "indestructible" nylon type stuffs are no match for my furry shark. This ball has stood up to him like David. He loves the crunch and it is so much more tolerable than a squeaker. These will be a staple in his toy box - Chuckit toys are really the most durable dog toys I have found in three years.

Dogs love them
Style: Ball, Size: Medium (Pack of 2)
Our dogs love these. What’s great is that you can add more plastic (like from water bottles) if the plastic starts to fall out from the center. If you have a chewer, though, these won’t last you long. Our shepherd mix loves these and then starts to pull the rubber apart the more she plays with it. Our other dogs treat it normally, though, and those ones last forever. They also get some decent height when bounced, and they make a unique whistling noise when thrown.

Our pup loves the cronch cronch!
Style: Ball, Size: Medium (Pack of 1)
I bought our 15 month old Coton several Chuck-It toys on an Amazon deal. He is incredibly playful, mischievous, and ball/toy obsessed, especially for anything that makes noise. He can also be very destructive so I love how durable most of their products are - they’re among our longest lasting toys and worth every penny. We have yet to take them to the dog park, but they’re a perfect size for sharing in play time. And they are keeping him busy at home - that’s a good thing.
He loves investigating the crunchy-cronchy-crinkly sound which is a nice change from squeakers. It can withstand his destructive chewing well-being, gentle on his little teeth. I love that. Chuck-It is thinking outside the box with a variety of balls to keep dogs engaged! I do worry about the crinkle plastic inside because it is accessible because of the air holes and it feels a little sharp. So this will have to be an at home toy so we can monitor his play.
