everything does. theoretically the only thing that does not refract light would be something that is pure black, although it is doubtful it is physically possible to make something that does that.
Additional answer
I presume you mean balloons. I also think you might mean reflect rather than refract, because why would a balloon refract light?
When the light is incident on the air/glass interface (or any interface) perpendicular to the interface it will not be refracted.
Dark colors and flat black do not reflect light well. Carbon Nanotubes are considered the worst for reflecting visible light.
Nothing except a black hole reflects no light. In everyday life, dull, black objects reflect very little.
Mirrors and other shiny surfaces.
The earth does not emit light, but it does reflect light from the sun.
A prism refracts light, and a mirror reflects light.
Glass reflects some of the light that hits it, absorbs some of the lightthat enters it, but 'transmits' most of the light that hits it. That's whyyou can see things through it pretty easily.
Light doesn't reflect light, nor does any other electromagnetic radiation.
Planets cannot emit light. They merely reflect light from nearby stars.
No, invisible things do not reflect light. But again, invisible things do not exist.
The moon reflects the suns light and things on the eart do notreflect it because it is at an angle in which the light does not reach earth. So if the light falls on the earth at night there would be light but because it not reflect it on earth it is dark at night.
Things with shiny surfaces reflect light :)
Any object that is black will theoretically not reflect any light.
Any object that is black will theoretically not reflect any light.
Diamonds
(almost) everything reflects light.
They are smooth reflectors that do not diffuse the light.
because some stuff doesn't reflect light. most dirty things probably don't have those materials.
mirror and glass
Water surface glass
Mirrors reflect light, lenses dont
