Paper helicopters flutter because the air gets under them and pushes them up against the natural gravity that is pushing them down. If made right these can flutter and fly quite a distance before finally coming down.

This happens because the heating wires heat up the air around them. This air is less denser than the surrounding, and so it rises up through the top of the heater. If the paper decorations are above the heater, they will definitely flutter because the air is coming through the top.
Paper decorations can flutter when placed above a hot room heater due to the rising warm air currents generated by the heater. The heat causes the air to become less dense, leading to upward drafts that can cause lightweight items, like paper, to move or flutter. This effect is more pronounced if the decorations are not secured and are made of lightweight material. Adequate placement away from heat sources is advisable to avoid potential fire hazards.
