Why does the triangle tower have no shadow?
Everything has a shadow. I think maybe because the shadow is cast upon it's self. Every object that stands in light casts a shadow, unless that object is light (produces light). A light bulb illuminated on a sunny day,has no shadow of the illumined parts. A flashlight in the sun light is a waste, a flame from a lighter on a sunny day is almost invisible. If an object casts no shadow, then, that object is light. I like to describe it as, (concerning people) a humble person casts no shadow.
What is the difference between a shadow of an object created by a small light source and the sun?
Shadow from light source always bigger than object but shadow from the sun is the same size as object. Great different is due to the distance of light source. Size of shadow is double at distance x 2 source to object. Shadow is always bigger than object. You will notice your shadow is bigger in light bulb or stadium spot light but the shadow from sun is the same size as object. This is due to great distance from sun to us (150 million km approximately) the double distance to see our shadow to be double is at 300 million km from the Sun. at merely 10 m or 100 km is almost no distinguishable different in shadow size to the object. We then presume shadow cause from sunlight is equal to the size of the object.

How can you learn whether or not a material can conduct electricity?
You need a battery, a light bulb, and three pieces of copper wire, as well as the thing you want to test. Create a circuit by connecting each object to two others with the copper wire. Place one end of a copper wire on the positive side of the battery, the other end on the bottom of the light bulb. With the second wire, connect one end to the side of the metal part of the light bulb (where you see the ridges), and the other end to the object. With the last wire, connect one end to the object and the other end to the negative side of the light bulb. If the light bulb lights up, then the object is conducting electricity. If you have a large light bulb, it won't show as much light, or maybe no light at all, even if you have a conductive material. It is better to use a smaller light bulb for smaller batteries, so you can see the light.
Can you use a light bulb to see if it's a battery?
