Using the black icing outline the outside of the shape. Split the icing into 5 small bowls and colour them using gel food colouring. Whip up a batch of royal cookie icing, I have two recipes one that uses fresh eggs, the other uses powdered eggs. Once set push down on the outside of the cookie cutter to remove it. Using a spoon spread some chocolate up the tube at the bottom and then leave it to set. You can get these for holding up balloons, or you could use a pencil or anything long and cover it in plastic wrap. Place a strong plastic tube into the centre of the chocolate. If you don’t have a cookie cutter grab a disposable round plastic food container and cut the base out of it. Fill it with melted compound chocolate, you can use real chocolate containing cocoa butter if you prefer but you’d need to temper it. Put a round cookie cutter onto a plate or or cake board that you are intending to serve the cake on. Flip the rockets over and bake for 5 minutes more. Roll that out in the same way to make a third rocket.Īnd bake those in the oven until lightly golden. Leave the rockets on the bakimg paper and remove the dough that is around them. Put the rocket shape template on top and cut two. Remove the top layer of baking paper and dust the dough with a little flour. Put the dough in the middle, add more baking paper on top and using a rolling pin or anything flat squash the dough down to the level of the chopsticks or whatever you’re using on the edges. Put some baking paper on the counter and add two even objects on either side, I used paint stirrer sticks but you could use thin books or chopsticks. Finally add the flour and mix until just combined. Mix together the sugar butter and spices, do not whip air into this mixture just mix together).Īdd the egg and stir well. Preheat the oven to 180C (356 degrees Fahrenheit).

Application of a weak electrical current subsequently destroys the molecules that are blocking the holes, allowing the sensor to be reused.I have designed this rocket ship cake to be easy to make even if you’ve not made cakes before and don’t have cake decorating equipment at home. Therefore, by monitoring the electrical signal produced by the sensor, it's possible to measure the concentration of the targeted metabolite in the wearer's sweat – and concentrations in the sweat typically correspond to those in the bloodstream. This means that not as much sweat will be able to get through, so a weaker current will be produced. However, if high levels of the metabolite are present in the sweat, the molecules will plug many of the holes.
When sweat comes into contact with that polymer – if little or none of the metabolite is present in the sweat – the liquid flows through the mostly open holes, creating a strong electrical current when it reaches the other polymer underneath.
What results is a polymer sheet containing tiny molded holes which are the exact size and shape of the molecules. The imprinting process involves embedding molecules of the target metabolite within the polymer while it's still in a liquid state, allowing the polymer to set to a rubber-like consistency, then using a chemical process to remove the molecules from it.

Importantly, forming a layer between that film and the skin is a second polymer that has been molecularly imprinted. Seeking a better-performing alternative, the researchers designed a sensor which incorporates a polymer film that generates an electrical current when it comes into contact with sweat. The antibodies were a bit more versatile, but they could only be used once. Unfortunately, though, the enzymes could only detect a relatively small number of metabolites. Among other things, unusually high or low levels of certain such chemicals could indicate specific disorders that require treatment. Previously, Gao and his team had created sensors with embedded enzymes or antibodies which reacted with specific metabolite chemicals in the wearer's sweat.
The experimental device was developed by a team at the California Institute of Technology (Caltech), led by Asst. A new one, however, utilizes a "molecularly imprinted polymer" to be much more useful. Although there are now a number of skin-worn sensors which identify metabolites in sweat, the technology is limited in what it can detect, plus the sensors often aren't reusable.
