A liquid prism containing water as the medium is both theoretically and experimentally ``investigated. It is confirmed that the dispersion power of the prism with an apex angle``of 950 is about 5 times higher compared to that of the prism with 60o apex. Using the ``950 prism, a simple direct-vision spectroscope was constructed having a fairly high s``pectrum resolution. This model offers an extremely low price spectroscope of high ``quality suitable for physics education especially in less privileged countries.
