Abstract: An air brush marker includes a marker barrel having a first end and a second end, with a pump disposed at the first end of the marker barrel and a hollow nib disposed at the second end that is configured to absorb ink. A filter is disposed within the marker barrel, is configured to absorb ink and is positioned in contact with the nib. A tube is disposed within the marker barrel and provides an air passage extending from the pump to the nib. The pump is configured to supply a burst of air through the tube and the nib such that ink particles are sprayed out of the marker at the second end in a generally dispersed pattern.

Abstract: An embodiment of the present invention provides a toy roller coaster assembly having magnetically attachable track sections and an integrated audiovisual system. The assembly can include a magnetic lift, a magnetic bridge, and a magnetic U-turn. A controller can control the frequency by which a magnetic lift delivers balls to an uppermost track section and can produce audio and/or visual effects in response to signals from sensors that detect passing balls. Joint members of the assembly can magnetically connect the track sections to each other and to a plurality of vertical supports, to provide a variety of configurations. The controller can generate voice and music samples, sound effects, graphic displays, animation sequences, and video clips in conjunction with the motion of the balls through the circuit of the roller coaster assembly.
