Weird & wonderful

A remote-controlled party cooler with a surprisingly full-sounding speaker, not cutting edge but cleverly put together.

A wand that lights up its tip when shaken and turns off when shaken again.

A self-stirring cauldron mug that he found surprisingly vigorous at stirring his tea.

Shown briefly as the first Harry Potter gadget, with no real judgement given beyond a joke about it not being pretty.

A golden snitch with a fluttery sound that turned out to be held up by a thin string behind his ear.

Genetically edited hornless cows that accidentally contained bacteria DNA and had to be incinerated, rated 8 out of 10 for fail.

A 1950 kids' play set with real radioactive materials, which he rates 10 out of 10 for stupidity.

A working oven for children that was recalled after kids burned their fingers, though he marks it down as a fail since newer models are saf…

A chess robot that fractured a seven-year-old boy's finger, followed by poor responses from officials; 8 out of 10 fail.

Looks cool on a custom car, but you will struggle to explain it to police who pull you over for imitating them.

So powerful it is classed as a burning laser, and dangerous to eyes.

Just a lighter, but looking like a real gun almost guarantees trouble.

A self-built pen plotter that drew perfect circles and a cat better and faster than he could, earning a nine.

A strobe-light illusion that makes water appear to flow upward, which he found hypnotic and rated 8.5 out of 10.

Pricey but gives remarkably precise, thin and smooth slices, and works brilliantly with kinetic sand.

Quick and effective at slicing apples, but more alarming than satisfying.

A cheap kitchen gadget that worked well enough to earn a seven out of ten.

Surprisingly effective, clean and pleasant way to mix a drink with a whirlpool effect.

Smooth and well balanced but not worth around fifty dollars.

A shiny pen whose whole structure changes when clicked, which he found interesting but did not score.

Unexpectedly fun object that finds equilibrium when spun, though the score was cut off in the transcript.

Many mechanisms create a constantly changing pattern, earning an easy eight.

A normal spinner with a slightly more unpredictable motion, scored six out of ten.

An elaborate sand toy that looks cheaply 3D printed for 200, though the moving bearing was neat.
