Copper dendrites form during electro-deposition

The distance between the Cu electrodes was about cm and voltage was 2.4 V, but you can do this experiment with 5-10 cm distance which can be already filmed with an ordinary camera. Of course you would need higher voltage, probably 10-20 V DC. You can experiment with CuCl2 solution concentration to get wider structures. Any microscope is suitable with magnification range from 1x to 5x. You can even use a DSLR with a macro lens.

U.S. Soil Grows Wind Power Garden
by Michael Keller
Wind farms have proliferated across the American landscape over the last four decades. According to the U.S. Energy Information Administration, one wind farm existed California in 1975. It produced enough electricity to power around 4,100 homes. By 2012, 815 wind farms were pumping out enough power for 15 million homes.

Ganymede and Callisto are similar in size and are made of a similar mixture of ice and rock, but data from the Galileo and Voyager spacecraft show that they look different at the surface and on the inside. Just like Earth and Venus, Ganymede and Callisto are twins, and understanding how they were born the same and grew up to be so different is of tremendous interest to planetary scientists.

Ganymede and Callisto’s evolutionary paths diverged about 3.8 billion years ago during the Late Heavy Bombardment, the phase in lunar history dominated by large impact events. Impacts during this period melted Ganymede so thoroughly and deeply that the heat could not be quickly removed. All of Ganymede’s rock sank to its center the same way that all the chocolate chips sink to the bottom of a melted carton of ice cream. Callisto received fewer impacts at lower velocities and avoided complete melting. Ganymede is closer to Jupiter and therefore is hit by twice as many icy impactors as Callisto, and the impactors hitting Ganymede have a higher average velocity.

Scale of the universe

Scroll to your hearts content from the Planck length to the diameter of the observable universe - click on any object and it will open an info box - I can’t imagine how much work must have gone into this. A few surprising things: Pluto has a smaller diameter than the width of the USA and Vatican city can fit in central park multiple times.
