We designed 'the Pumprella' to minimize the inconvenience of carrying a heavy umbrella. The Pumprella is a light and portable umbrella which is made from tubes except its handle. You are able to use it after you lift the lid of the Pumprella and pump air into a tube. In addition, kinetic energy in store while you are pumping can function as lighting, so it can reduce a danger of accidents on rainy nights.
