Low Temperature All-metal Stirling Engine Model Toy for Developing Intelligence

EASY OPERATION: Set this engine over a mug of boiling water; wait for 20 seconds; give the flywheels a gently turn; it will be smooth-running quietly and slowly for around 20-30 minutes. Power piston goes with faint sounds when the flywheels is rotating, which even quieter than the tick tock sounds of your clock. This model needs a relatively high operating differential between the two panels (we will explain why in description), so taking BOILING WATER as heat source is a must.
UNIQUE AND GRACEFUL: Twin flywheels are totally symmetrical on both sides of the nicely curved arm and run simultaneously when you give them a gentle turn. Hollow-out parts cut into flower shape beautifies its appearance a lot. 4 aluminum alloy feet & 4 golden fasteners on the top panel truly give this silver engine a more eye-catching appearance. Special anodizing treatment ensures this engine shining for years. It will be a great ornament on your desk.
AN ENGINE WITH FINEST WORKMANSHIP & MATERIAL: Essential parts all made by SUJ2 bearing steel are of precision up to 0.002mm tolerance. Ultra high hardness alloy with high-precision size enables those parts to be wear-resistant and interact with each other smoothly. The bent rod is of high hardness after the heat treatment, strongly stable to keep 2 aluminum alloy flywheels perfectly in the right position. It’s designed to, and we do hope and believe it will, accompany you for years!
WIDE APPLICATIONS: It will be a great conversation starter for everyone around you; a cool desktop piece amazing your friends and colleagues; a great gadget to kill time when boring; a relaxing stress relief physics toy for people in the office; an impressive gift for your families, friends, especially for engineering/physics lovers. It can be used for teaching physics, great to display basic principles of a Stirling engine and to show the art of design.
FANTASTIC GIFT FOR EVERYONE: If you’re always stuck in a choice that prepares a unique gift for someone you love, this shinning engine could be a remarkable one impressing them, gorgeous and funny. Especially for those who owned a Stirling engine before, you should try this one and I guess you will not feel regretful.

 

Working Temperature Differential of this engine is around 40-50°C/72-90°F, much higher compare to our other engines. The main reason is we use a power piston made by bearing steel other than glass! Weight of the power piston is about 26.5g/0.93oz while a glass one is about 6.5g/0.23oz.

To play this engine, simply pour boiling water into your mug, wait for 20 seconds, then give the flywheels a gentle push, it will then rotate by itself for about 20-30 minutes. I don't know what will you do with the engine, for me, every morning when I get to my office, after making sure my boss is not somewhere nearby, I will put mine on mug and watch it rotate for a while.

It is not designed for kids. If you are a starter at Stirling engine I do not suggest this one; if the one you send it as a gift to is not very close to you I do not suggest this one too since it is expensive. In both cases you have wide choices of LTDs in our store. This is an engine that will accompany you or those you love for years. If it is a gift, he/she will think about you every morning:-)

It’s not necessary to lubricate any parts to get it going faster. Finest material with finest workmanship ensure its durability. This is an engine work in good condition for many years without lubrication.

Not real sweet, but no sugar
I have been taking Metamucil with real sugar regularly for 20+ years. I became concerned about the amount of sugar I was consuming daily and cannot tolerate aspartame. So, I jumped to buy this when I saw Stevia. I quickly noticed that this version is not sweet. It’s sort of bitter. Also, the texture is different due to not having sugar granules mixed in. It also converts to a gel like texture quicker. I later noticed you use less of this product per serving than the one with sugar (read the label!). I have found the best way to take this is to very quickly (seconds) consume the serving after adding water. Don’t wait too long. I down it like taking a shot out of a shot glass followed quickly by a glass of water. After a while, I got used to the flavor. Overall, I am pleased I am consuming much less sugar and really don’t notice the change anymore.

This product is very important to your well being.
The Metamucil is everything I hoped for. If you’re concerned about your sugar intake then I suggest the one with Stevia. Yes the one with natural sugar tastes the best but once you graduate to 3 times a day that’s a lot of sugar. I would follow the directions. Start with once a day then after 3 or 4 days you’ll find twice a day works nice. I’m on my 4th week so a few days ago I started 3 times. I’m very pleased with the way I feel. Think about it, we take care of our cars better than ourselves sometimes. It’s so important to take care of your digestive system. Have a good day. 😁

Great flavor, less calories than real sugar, thickens very quickly.
I usually get the real sugar version of this rather than this one with Stevia. I have it every morning just to supplement my diet with fiber and the version with stevia is only 30 calories vs 80 for the one with real sugar. I mix it with unflavored protein powder in a shaker cup and this one thickens very quickly. So quickly that I add water after every quarter of the container that I drink and re-shake. Otherwise it gets so think it won’t even come out by the time I’m halfway through. Once I figured that out it’s no big deal but makes it so that I won’t take it in the car to drink on the go.

IBS C must have!
I have been suffering with OBS C for a very long time now and my doctor through Amazon Care (if you haven't downloaded that app yet, do it now) recommend that I take magnesium and the Align probiotic with breakfast and Metamucil in the evening before bed. I am finally feeling better and have not had any issues using the restroom! I recommend for sure. The taste is meh but I would rather down something that doesn't taste great as long as I feel better anyway!

Very functional for our family - We ordered a second one
Color: Black
We were happy to stumble on this paper towel holder after trying a few that just either didn’t look great and didn’t work well. We really like the black matte finish and the fact that the base is pretty heavy so you can actually tear off a paper towel without the whole thing toppling over. The spray/cleaner is an added bonus to have right there also. It’s awesome for craft time and cleanup after kids. We purchased one for both our kitchen table and our rental property and they both function great and have been holding up very well. Happy with the purchase!
