Product Name: Stirling Engine Model
Color: As shown on the picture.
Material: Metal,Glass
Usage:
1. Security start step
(1) Put the engine model in a horizontal position.
(2) Turn the flywheel gently with the hand, check whether the flywheel is running smoothly if there is a strong sense of astringency, check whether the connecting rod is connected to normal, whether the piston in the air cylinder and the spindle on the copper sleeve have oil if there is a dry cloth or toilet paper with oil. Wipe the piston and the outer wall of the spindle, confirm that there is no oil stain or foreign matter to ensure that the flywheel runs smoothly.
(3) Check whether the two crankshaft angle on the flywheel is 90 degrees (the crankshaft is at the bottom or the most right side of the crankshaft at the bottom), if it is not to be adjusted in parentheses.
(4) The alcohol lamp is moved to the hole of alcohol lampholder, and the alcohol lamp is ignited on the premise of confirming safety.
(5) After heating for 60 seconds, start with your hand gently toggle the flywheel until the flywheel can run automatically.
(6) The whole process of heating must not touch the main cylinder (high temperature danger!).

(3) If the engine model is cooled down naturally, please keep the engine where the child can't get it.
(4) Children should use the engine model under the care of adults, so as to prevent scalding or accidentally breaking the glass.
3.Matters of attention
(1) When alcohol is added to the alcohol lamp, please confirm that the alcohol lamp is in the state of extinction.
(2) If alcohol is inadvertently sprinkled on the model floor or on the desktop, please wait for the alcohol to evaporate completely or dry the alcohol, and then ignition.
(3) The wick of the alcohol lamp can not meet the test tube, and the light core will produce water vapor when it burns. If it meets the test tube, it will break the test tube.

Dogs only toy that has not broken.
Size: Extra Large Size 4, Color: Rainbow
I've ordered them in 6, 7, and 8 inches I think. She is an aggressive chewer who had destroyed every toy I've given her. But not these! She has chewed off every strap which I've promptly taken from her to avoid her eating them. But the ball itself is chew resistant! I use the small 6" one to play around inside with her and the larger ones to play outside. My puppy absolutely loves playing "soccer" with these. Worth the money IMO.

My dog LOVES this tiny tug ball
Size: Medium(6")
A lot smaller than I was expecting.. BUT my dog doesn’t mind at all. She seriously loves this thing. It goes flat fairly quickly, but that’s what happens with all of her soccer balls, no matter the size. She’s a pitbul catahoula mix and has a strong bite. Considering my dogs chewing abilities, I’m fairly impressed by the durability of the ball, though she chewed through all but one of the rope handles in about 2 seconds. All that said, it’s one of her favorite toys(she’s 13 years old)
