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. The SpillNot is a cup holder with a difference. Its design means that it is difficult to spill the contents of any glass or mug that is placed on it. You can swing the SpillNot as much as you like and the drink stays in the mug! This is particularly useful for carrying hot drinks, which you cannot place in your lap. 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.
Carrying an Open Beverage with the SpillNot. Now suppose an open beverage is being carried on a SpillNot rather than directly by the cup handle. Instead of abruptly moving the handle of the cup, the person abruptly applies a horizontal force, Fh, to the top part of the SpillNot handle. Be careful however, the velocity changes throughout the circle. It will reduce error to use only the top half of the circle. In that case, vsemicircle= πR/t. Post lab analysis might involve comparing g with v2/r and accounting for error; which is usually about 15%. The SpillNot has a curved plastic body with a non-slip platform for cups or glasses, and a fabric handle that you can slip your hand into. The looped, fabric handle prevents you from applying a lateral force to the liquid in the cup, so the liquid doesn’t spill (the science is quite complicated!). Testing out the SpillNot The SpillNot is an ingenious gadget that will let you carry an open beverage without spilling it. With a little bit of practice, spin a cup of liquid around in a circle without even losing a drop! The forces in action will fascinate your students and challenge their analytical reasoning. If you fail to return any VAT exemption forms to us we WILL charge your card for the outstanding VAT.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. A person may display a poor appetite, but underlying this might be depression, difficulty communicating, pain and/or tiredness. In later stages of dementia a person may not recognise food and drink. Concentration may also be poor. Keeping eating times regular, simple, calm and familiar might help. The cool physics of the SpillNot is that the liquid does not spill or slosh in the cup and the cup does not tend to slide on the SpillNot as it’s carried, even if it is swung all around. Why not? The answer is that the loop handle (let’s think of it as a ‘thread’) is very flexible and cannot deliver a lateral acceleration to the cup (because it has no ‘sheer strength’), which is what usually makes liquid spill from an open container that is not tipped. 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. After 7 years of marriage, this morning I had my first ever cup of tea in bed from my husband, made possible by the SpillNot. My husband is tetraplegic and so carrying things between rooms, especially drinks, has always been very difficult. But not anymore! For me, it’s always the small things that mean the world and I felt very spoilt this morning. Thank you for a fantastic product….I think I could get used to this!
Jake: Honestly think this thing will work really well. I was thinking ahead, and I made you some nice chai tea. But you can't drink it unless it survives the spin test. If it's on the ground, you can't drink it. Rob’s work has been extensively recognised by different awards such as the Stelios Award For Disabled Entrepreneurs In The UK 2011, The Inclusive Technology Prize, and The Disability Power 100 2020. f) Measure the horizontal radius (if the velocity is sufficient then Rhoriz = R is nearly true, otherwise Rhoriz = R cos θ)Important Note: It does NOT include a frail elderly person who is otherwise able-bodied or any person who is only temporarily disabled or incapacitated, such as with a broken limb. 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.

We do NOT decide if an item is or isn’t exempt & we don’t make any more or less money if we charge you VAT or we don’t charge you VAT. Rob tested out the SpillNot at home. His wife, Jo, was delighted to get a cup of tea in bed on Mother’s Day: Jake: This is so great. It's like when you go to the tailgate and you wanna do big windmills with your drink. It won't fall. Medha: So I think that this is definitely a product that I would get if you're really clumsy or if you just have a hard time holding a cup of any liquid whatsoever. Don't have to worry about it spilling. It's amazing.

If you have not had an opportunity to discuss your eating and drinking difficulties with a professional, you are strongly advised to seek an assessment of your situation. 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. More generally, swinging does not tend to cause the cup to slide off the saucer or liquid to slosh in the cup because the only force acting in a direction that is not parallel to the sides of the cup is the force of gravity, and gravity is equally accelerating all molecules of the saucer, cup, and liquid in the cup. Active Hands discovered the SpillNot a few years ago and identified that it would be useful for those with a disability: enabling the user to carry a cup of tea without spilling it when using a wheelchair or if they are unsteady on their feet. It was not designed as disability product and so the appeal was there for many able-bodied users too. Who wouldn’t want to swing a cup of tea around in a circle without spilling a drop!
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. Alternatively, one could use the tilt of the SpillNot to determine the force. This can be accomplished by perhaps taking a picture or still-frame of a person swinging the apparatus. Then, with a protractor, measure the angle at which the rope falls below the horizontal. One can then compare a and v2/R by using tan(Ɵ)=a/g If you find the idea of wearing a bib difficult, you might like to consider wearing a standard cooking apron, although they are not generally waterproof and will need washing.Not all of our products are eligible for VAT relief, so we are obliged to charge VAT for those products even after you complete this form.
