Step 3: Safety alert ...
NOTE- adults should take these spikes away from kids (OR AT LEAST SMOOTH OVER THE SHARP END) as boys especially will promptly play "warriors" with them & eye damage could arise. The hollow tubes tempt as "pea shooters" as well ...
A more peaceful "waste not want not" could involve blocking the drainholes with hot melt glue -
Step 4: Rain gauge !
- and there's an instant RAIN GAUGE ! Of course it should be higher off the ground to prevent splashes- maybe use 2 tubes to make a taller one?
Step 5: Linked tubes?
The lamp support tubes in fact will link together quite well, perhaps to suit structural "extension" challenges. Here some Kiwi 8-10yo. scouts try to touch the ceiling with about 20 of them!
