Abstract: A toy doll includes a body having an opening simulating a mouth and first and second electrical switches, each switch being disposed proximal to the simulated mouth and activatable by an object inserted at least partially into the mouth. A speaker is attached to the body. An electrical circuit including an integrated circuit chip is electrically connected with the switches and with the speaker. A base configured as a feeding tray is disposed externally of and is detachably connected with the body. The base has three external switches electrically connected with the circuit chip. The circuit chip has a plurality of memory registers, each register storing a separate signal corresponding to a separate audio message. The chip is configured to randomly select a prompt signal from the memory registers and to transmit the stored signal to the speaker. The prompt signal prompts the user to select a specified one of the switches. The chip is also configured to compare the selected switch with the specified switch.

Abstract: A jump rope which produces bubbles as it is rotated. A hollow liquid containing handle is located at each end of the jump rope. A bubble diffusor is positioned near each handle. A flexible liquid transporting tube connects each handle with its bubble diffusor. Each bubble diffusor includes coaxial tubes having an annular space between the tubes. Aligned openings are formed in the inner and outer coaxial tubes. The liquid bubble producing solution moves from the handles to the annular space between the tubes of the diffusor as the rope is rotated during jumping. The liquid bubble producing liquid spreads across the openings. Air passing through the openings in the coaxial tubes produces bubbles.
