You can perform an orange to black chemistry demonstration using materials commonly found in stores. The reaction appears to be similar to the Old Nassau reaction, but uses greener reagents. This is a great demonstration to do around Halloween time.
Chad Husting uses a few simple gas law experiments to introduce his students to the particulate level of chemistry.
The familiar soda fountains that can be produced by adding Mentos candies to plastic bottles of carbonated beverages can also be produced by adding objects to carbonated beverages in aluminum cans. A variety of simple methods for producing soda fountains from cans are described.

Summertime means doing chemistry experiments with flowers found growing in the yard...
A lab practical with an escape room story turned out to be a great final exam.
Some explorations and explanations regarding superconductors and the quantum levitation (also known as quantum locking) experiment.
Good day, gentle readers:
Let me start by telling a story that, at first blush, has nothing to do with chemistry teaching.
Beautiful, metallic mirrors of copper or silver can easily be formed in test tubes. Simply add the appropriate metal salt to a test tube, and heat! These reactions should be performed in a fume hood.
Doug Ragan has been working with the Alchemie team -- founded by a former chemistry teacher, Julia Winter -- for a number of years. They have been working over the last year on a new project, named Kasi, which delivers sound-based feedback to students as they learn with tactile pieces on a magnetic whiteboard. The goal is to build an accessible learning system that helps ALL students learn, and is particularly important for those with visual impairments.
