Jake: But does it really work? So I am known to be that guy that spills drinks because I'm clumsy, I got a lot going on in my head, so this could be a big deal.
Rob tested out the SpillNot at home. His wife, Jo, was delighted to get a cup of tea in bed on Mother’s Day:The SpillNot employs simple physics in keeping your coffee cup from spills and breakage. By carrying the moving cup containing liquid, several forces act on the cup, and consequently on the liquid contained inside. If balanced forces are applied to a cup of liquid (…whether at rest or moving with a constant velocity), the liquid remains virtually undisturbed. However, once an unbalanced force is applied to the cup (ex. A force greater to the right than to the left), the cup will accelerate. The liquid’s mass will not accelerate with the cup due to its fluid nature; instead, accelerating the liquid will cause the liquid to spill out of the cup; due to inertia and the liquid’s inability to keep up with the accelerating cup.
Difficulties with initiating or carrying out movement may occur in later stages. This might affect all actions required to get food to the mouth and then to eat it. Verbal prompting and physical assistance may be needed. Finger foods or less ‘messy’ foods might help. As dementia progresses, swallowing difficulties (dysphagia) become more common. If a person has difficulty chewing and swallowing, you are advised to seek an appointment with a speech and language therapist. Having softer foods might help. f) Measure the horizontal radius (if the velocity is sufficient then Rhoriz = R is nearly true, otherwise Rhoriz = R cos θ) Jake: You're gonna be on the ground with a straw, just slurping up the results of your failed experiment. All right, Medha, let's have some tea. Tea time, tea time, everyone, gather round. It's tea time. Grab your crumpets. Although the problem of why coffee spills might seem trivial, it actually brings together a variety of fundamental scientific issues. These include fluid mechanics, the stability of fluid surfaces, and interactions between fluids and structures (we'll set aside the biology of walking for now). The SpillNot is a cool tool for getting your students interested in the everyday physics behind why drinks spill while we're carrying them and what has to happen to prevent spillage.

Some assistive technology needs to meet Australian or other standards. Standards may relate to materials, manufacturing and installation. Products that meet Australian or international standards will have written certification. To find out if a product meets Australian Standards ask the supplier to show you the certificate. For more information about standards also see These support the user's forearm in a trough-shaped device that tilts to bring the hand down and upwards. Some are also mounted on a swivel that glides in the horizontal plane, and powered versions will raise and lower the whole device. Jake: Let's pretend we're at the clubs right now. We got our cool drinks at the club. We're just sittin' here like, "Oh, hey! 'Sup friends at the club? We just got our drinks. They ain't spillin' anywhere. Oh, oh!" - Pretty good! It works pretty friggin' good. But we haven't yet done the full windmill that we saw in that commercial earlier. That's the big test. At rest, the surface of liquid in a container is perpendicular to the direction of the force of gravity, Fmg, as is depicted in the above drawing. However, if we consider the reference frame of the cup during acceleration, the liquid is subject to two forces, Fmg and Fl, which act in combination. To account for both these forces, we can compute the net force, Fnet, by vector addition. If we align the two vectors, Fmg and Fl, tail to head, then the net force is the vector, Fnet, which has length and direction extending from the tail of the first vector to the head of the second. In reaction to the acceleration, there is a realignment of the surface of the liquid in the cup to be perpendicular to Fnet, rather than Fmg, as depicted above in the drawing. The larger the force Fl, the more tipped the surface will be while the cup is accelerating. If the surface is sufficiently tipped, the side of the cup will not be tall enough to retain the liquid, resulting in a spill.
Eating and drinking both involve many different decisions, actions and movements. They are complex activities and can be disrupted in many ways. For anyone, whether able bodied or not, it is best to be sitting upright in a well-supported position. You should be sat close to the table or tray, which should be roughly at the height of your elbow. This means that the table can be used to support your forearms if required.If you find that eating and drinking causes spillage onto your clothes, you may want to consider wearing an apron or bib. There is a large range of designs, some more discreet than others. They are available in disposable plastic or washable/wipeable materials. Consider what is the best fastening system for you, whether the bib/apron pulls over the head, is tied, has a Velcro hook and loop system, a popper, or some other way of fixing.
You may be provided with equipment and services as a preventative measure, before a needs assessment is done. If, on assessment, your needs are high enough to qualify for help from the local authority, they will then look at your income and savings to see whether you will need to pay towards any future services you receive. These services might include disability equipment including alarms or telecare, adaptations to your home, help from a carer, or the delivery of meals or residential care. with a physical or mental impairment which has a long-term and substantial adverse effect upon his/her ability to carry out everyday activities;h) Compare T with mv2/R, determine the percent difference, account for experimental error. (One such error is the assumption that either R or T is horizontal or that the mass of the apparatus is all the way out at R, which it is not!) Diagnosing errors is an important skill in physics. Note, that the centripetal force is only caused by Thoriz = T cos θ.
